No studies on this area, so you have more street cred than me on this but....

You can't kill an idea, but you can severely maim it for a generation or 2.

We have clear examples of authoritarian states successfully suppressing specific topics. It's not so much about killing it as creating a line where consequences start happening.

China is one example, where being too vocal about certain topics online can land you in a police station interview.

I don't think we should be overly confident that similar things can't happen in the US or EU.

And indeed, in the US we're seeing the administration successfully pressure changes at educational institutions for example. We're already uncomfortably far down this road imo.

Nothing changes the underlying asymmetry that one side is fighting to be welcoming of the unfamiliar while the other side is fighting to remain in fear of it. The latter will always spiral downward, giving in to it is a non-starter.

Ignoring what is "morally wrong", is it proper to blame Trump for doing the same thing that his predecessor did, with the only distinction being in the (completely legal) beliefs themselves?

Does "radical traditional Christian groups" include the ones bombing abortion clinics and killing doctors? If so, then it does seem warranted. But alas, Christians can only be victims according to their persecution complex so it's everyone else's fault, and, those hurt by their lashing out clearly deserved it or something.

This is pure victim blaming.

Ah, yes, the old "don't do _that_, then the Republicans will do it too" -- as if this administration has been in any way constrained by the limits of any previous administration.

I'd ask for a citation of what Biden/Biden's admin actually did, but the Trump folks have been so busy disappearing things that the policy that I think you're referring to is now gone from the WhiteHouse.gov site and doesn't seem to be available via Internet Archive either.

Once again, in harmony, and louder for the people in the back: the both-sidesism is utterly misguided, plays into the Trump camp's hands, and just entirely fails to recognize just how not-normal and dangerous things are right now and they are just getting worse by the day.

It is already too late. There is no stopping this train, we are in for the ride to the end.

Worth noting the Nazis literally killed the socialist wing of the party to take it over as well. Fascists and authoritarians ultimately have no ideological allies but themselves.
