It’s a blessing and a curse. On the one hand, it’s easy to block out communities with racist, homophobic, and xenophobic views. On the other hand, it allows communities like that to become echo chambers and freely further their abhorrent ideals completely unchecked.
I don’t think the ban hammer is the most effective method of shutting down nazi shit, but it’s a hell of a lot better than shutting it out of sight and trying to forget about it.
