Unfortunately the internet has broken the social contract for a large swath of the country. They can find any truth they want online. Facts are no longer important, just (fake) data points that confirm their existing beliefs. The Republican Party has figured out they no longer need to acknowledge facts to win elections, they just need to support whatever idea their constituency is currently consuming from Fox News.

This election cycle it’s that “liberal” cities are overrun with criminal migrants and the only way to save the children is sending in the military. Constitution be damned.

This is what Republicans do. It is their job.

Their job is dialling for dollars to get re-elected. We are the product not the customer.

A big reason why Trump is firing anyone responsible for tracking or reporting facts.

I'm concerned that we're entering or living in some kind of modern dark age. Everyone in the world is part of one network (more or less) for the first time in human history, and information spreads like wildfire but there's no systems in place to make sure it's "good" information. That's being put entirely on individuals to decide for themselves (family, friends, etc be damned) while at the same time, Republicans are taking away any public services that help make informed decisions. Supposedly this means more freedom (or strength?) but really it just means more ignorance.

I really don't like that phrase. It should be "reality has a progressive bias". Progressive is the opposite of conservative. "Liberal" is a specific ideology, and will end up in a position somewhere on the progressive-conservative spectrum based on how progressive or conservative it is.

Specifically it is the ideology of Capitalism, representative democracy, the rule of law, etc... basically the ideology of the enlightenment.

This misuse of Liberal is easy to track the etymology. The colloquial usage of "liberal" does sound like an opposite of conservative, it's basically a synonym for "lenient". But colloquial usage is often totally incorrect in certain contexts, like this one.

People who use "liberal" as an opposite of conservative are just bad at type theory.

When one side is known for constant lies, documenting the truth will invariably look like bias toward the other side.

To say it's biased to the left requires some agreement on what scale to use and where neutral is. I don't think there is such an agreement.

One niggle with your linked article is it says it's biased because it goes on about Trump's impeachments and doesn't say similar stuff about Obama but you could argue that's maybe because Trump got impeached twice and Obama didn't, rather than Wikipedia's biases or lack thereof.
