The instance seems to be mostly right wing trolls. I know defederating is unpopular but I don't think much is to be lost in this case and it can save the mods some headaches.

Maybe these specific people will...
But the idea of ruthlessly filtering people out of your sight if they disagree with you rather than engaging in conversation is endemic. These people have zero interest in being challenged in any way, it's easier to press block or press the downvote button than it is to reply. The OP wants to cut off an entire instance because that's easier for their existence.
They feel like they're doing the right thing... but you can't convince them otherwise because they won't engage in any kind of debate. If you disagree with them they'll just label you as a bad person (OP suggested that someone, who disagreed with them, should go make an account on EH "because you sound like you belong there") and put you outside of their filter bubble.
Or, to Godwin this entire thing, you know there was another group of people who decided to label an entire group of people as a problem and to cut them out of society...
Ah, it's the American way to pretend other people don't exist. Not much can be done to change their minds.
Unfortunately, I like to argue with idiots. It's why I'm still awake at 3am instead of sleeping. 💀
