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.

I don't feel a need to stay up to date, no. But reading about what those idiots think doesn't hurt my ego or ruin my day. I just like to have an idea of what the "enemy" is thinking. I don't want to live in an echo chamber. The sub isn't even THAT bad compared to what I was expecting. They've got some gross posts, don't get me wrong. But it's not NEARLY bad enough to warrant defederating. Most of the posted content is moderate-right. Defederating is silly in this case.
Removing those that wish people were dead for existing doesn't create an echo chamber.
If they have users calling for violence and those users are not being banned that is one thing. If they have odious opinions on trans healthcare that's completely different.
De-federation should be used for instances that promote literal violence. Blocking should be used on communities and posters who have opinions that you can't stand.
We get it, you're straight.
