There are MANY center-right communities in the fediverse where you are allowed (even encouraged) to defend things like genocide, imperialism, colonialism, capitalism, US-style "democracy," and those who support them. This is not one of them.
On a philosophical level, I'd like the same, but I've seen what happens in communities that allow certain groups to take over.
Also, I personally live in a place where I'm constantly fighting for my existence, so I need a break from that fight to maintain my mental health, and I think a lot of others do too. For example, I know many people who've been oppressed by our nation. I feel like we all need a space to discuss without constantly having shit flung at us.
