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.

Exploding Heads have between 40-60 active users, you probably noticed two posters you find disagreeable.
Have you considered blocking the users or communities you find offensive?
I second this.
If the platform itself allows these users to participate then the platform is also an issue.
If you hang out with racists and don't argue against them then you're racist too.
