this resonates a lot. I am not sure how to handle this though. Next to our house (500m), the city government established a camp for “asylum seekers”. 100 men. Men only. How can I reasonable let my pre-teen daughters roam freely now? Id love to, but my gut feeling doesnt allow me to.

Maybe, back in the days, it was just a different time? A more high trust society that worked well?

Nowadays, we have news stories, where 70 year olds get stabbed by youngsters because they got lectures on their bad behaviour. When I was young, I had respect towards a 70 year old. Big time. Never would we have thought to pull out a knife…

Life changed a lot in recent years and not for the better on all dimensions.

Europe is still pretty save though. At least if you trust the statistics

techjamie•33m ago
Statistically, we live in the safest society we ever have. We see a lot of bad stuff happening because news reporting travels further and faster than ever before, amplifying the perception the world is going to shit.

Plus, now, basically every kid is running around with a phone that gives them access to talk to the police or their parents at any time. So it's going to be a lot riskier for someone to try anything against them. Even then, between 80-90% of sexual assaults are performed by people the victims already know, and around 30% of those are relatives of the victim.

shrubble•31m ago
I think it’s the importation of men from countries where rape is seen as natural and not illegal that’s the key concern here…
realo•4m ago
Wow. Are you for real?

I thought this kind of bigotry was only used by far right shit to manipulate feeble-minded people.

I'll be generous and assume this comment was not made by a human, but by a bot.

dghlsakjg•8m ago
Do you have any evidence or are you just basing your fears on feelings? Has there been a rise in sex attacks associated with this particular refugee housing?

You should flip through some newspaper archives from when you were a kid. I don’t know where you are, but I can almost certainly guarantee that there were kids attacking people back then too. Just because you and most you know would never have pulled a knife, doesn’t mean that there weren’t those that would. After all, you say the teens today attack old people with knives, but I really don’t think your teen daughters are stabbing people with knives.

How can you reasonably let your teen daughters out alone? Well, be reasonable. Find out if your fears are amped up by sensationalist press. Go meet your refugee neighbours. Quite honestly it sounds like YOU spend too much time inside.

roxolotl•1h ago
I’m reasonably convinced this explains basically everything currently attributed to social media, for children at least, and likely can also help explain some concern around birth rates and child rearing costs. Starting with the satanic panic the US has slowly closed down children’s lives because of concern that terrible things will happen to children if not continually under supervision. And the true is that yes sometimes bad things happen and have always happened. But if you look to many other countries they do not have the same extreme expectations of parents or the state to keep children’s lives locked down.
trallnag•38m ago
Does the term "satanic panic" also apply to the EU restricting internet access for the youth?
dghlsakjg•17m ago
Satanic panic was a very specific phenomenon in the US.

I don't know. Maybe this is going away in some places, maybe I just have my own anecdata, but my kids play outside unsupervised all the time, as do all the kids in my neighborhood.

I live in just a regular suburban neighborhood on the outskirts of small Metro. Nothing special about it at all.

Every time I see one of these articles I always wonder who they're talking about.

I always feel like this is just one of those news headlines that won't go away, but isn't quite tethered to reality, but people really like to feel bad about modern life and so we keep talking about it as if it's real. I suspect the real reason kids aren't playing outside, if there is one, is not because they can't, it's because they choose not to. Just as adults are no longer choosing to go to third spaces. Screens came for everyone.

rayiner•40m ago
This behavior is probably overrepresented in the bougie places reporters live. I dropped my daughter off at the mall to hang out with their friends and one of the moms followed them around the whole time. They're all 13!

> my kids play outside unsupervised all the time, as do all the kids in my neighborhood. I live in just a regular suburban neighborhood

Your kids are hardly free-range. Let me guess, there's no way for them to actually meaningfully leave the area (no train, bus, etc)? It's like dumping kids on a 5 acre farm and saying they can do whatever they want. hardly free-range in the way described in the article.

Presumably you live in a suburb for the reasons the person in the article checked in on the free-range kid.

my personal litmus test is if you'd let your 13 year kid explore Manhattan alone during the day. Many say no because it's dangerous, and yet Manhattan is safer than most American suburbs. just FUD all the way down sadly.

ghaff•9m ago
The usual contrast being drawn is kids wandering around a suburban area, walking to school, playing with kids in a nearby rural property. It's not hopping onto a bus to the city a few tens of miles away. You do see schoolchildren in Japan on the train by themselves but I'm not sure that's ever been very common in the US.
amazingamazing•7m ago
there's really no reason American kids in metro areas like SF, Boston, DC, NYC couldn't take a bus 5 miles away by themselves. when one comes up of an actual reason to why, it contradicts real statistics.

the biggest things parents should worry about is their kid being bullied by other kids during school, a supposedly safe place, and other family. strangers just aren't the major source of violence towards children.

Welp this week we in Phoenix are dealing with a report of a 17-year-old high school girl who boarded a light rail train (the one with security cameras and guards) and she was harassed and assaulted by a mob of boys on the train, presumably in front of human onlookers; she disembarked, and was assaulted some more.

She is now in a neck brace, and her mother is absolutely distraught, saying this is something she cannot fix for her beloved daughter. I am distraught as well that this could happen to anyone at all on the same train that I ride every week.

Plenty of trouble for a 13 year old in Manhattan. Even if it's not dangerous, you can find your own problems easily enough.
xtiansimon•1h ago
My free range childhood friends and I would have been all _get bent_ to that lady—even at 6 yro. I can tell you this because I was also getting a whooping at home from da for saying the same to my ma. I was a dreadful child.
jl6•55m ago
It’s easier to let kids play around the neighborhood when you know who the neighbors are.
amazingamazing•10m ago
most acts of abuse to family members are by other family members. ironically strangers are more likely to leave your kid alone than extended family.
phyzix5761•2m ago
That's a problem of access not familiarity.

I think this is more a data point towards the quiet disappearnce of community / the steady march towards pervasive isolation
Loughla•32m ago
Correct. There are no communities anymore, just groups of houses. You see it in the death of social and civic organizations, churches, and other community groups.

Everybody is an island. I don't know what has caused this, but it seems like it's happening in most 1st world countries. Anyone have insights about this?

metalman•37m ago
here in Canada, social service "baby snatchers" have destroyed basic community cohesion and along with many other wildly out of control beurocratic policing forces, such as the spca making having animals a huge liability, litteral special subdivisions, chicken police, horse police, and an enacted rock police to prevent the totaly illegal practice of picking rocks off a beach, but hey it is legal to pack granma into the back of a motor home and drive her to the government canabis store, get her wrecked, and then take her in so she can ask to be euthanized. cant make this shit up as they say.

My biggest fear of letting my young kid play alone outside is getting hit by a car.
neogodless•25m ago
When I was a kid I was taught not to walk in the street.

When you walk, you go in the opposite direction of cars and can see them coming and, if necessary, move off to the side more.

I know it's survivorship bias, but it worked for me.

Now I get that population density is increasing, and probably so is traffic. Though so are automatic safety features that cause cars to brake rather than hit things.

Are there statistics on vehicular fatalities in suburbs?

tomasphan•12m ago
Pedestrian traffic deaths are going down again after peaking in 2022. Accidents are less survivable in the US due to bigger cars and higher hoods.

Quote from CDC

During 2013–2022, U.S. traffic-related death rates increased a relative 50.0% for pedestrians and 22.5% overall, compared with those in 27 other high-income countries, where they declined a median of 24.7% and 19.4%, respectively. Across countries, U.S. pedestrian death rates were highest overall and among persons aged 15–24 and 25–64 years.

That's why you have an emergency backup child for redundancy in case of failure of the main child.
ocdtrekkie•26m ago
I remember when I was a kid I would bike to a park around a half mile away by myself, definitely before I was 13, and I admit it feels weird to suggest a kid can go to the park down just a single block alone today.

The funny thing is it'd be safer: Kids have cell phones now by like 7 or 8 in a lot of cases and can call for help! Back when I was that age if I got injured or something I might've had to knock on strangers' doors!

gehsty•9m ago
As a parent you feel the push and pull of not ignoring your child while also not mollycoddling them. For me let the kid do what they want - if your kid wants to stay home let them, if they want to climb trees and go off on their bike let them. Help them learn what is safe (which rods can they cross), what are their boundaries. Hopefully they get it, maybe they don’t. Don’t restrict access to devices or screens too harshly. Encourage games of any kind. Wear sunscreen.
