I like a few non-political sublemmies from lemmyworld because they are big. But the political ones are so toxic they literally allow citing mein kamf and dehumanizing Russians. Isn't it hypocritical for their admins to accuse us of "negativity" when they literally allow racism on their instance? The commenters on their defed post call lemmygradians hateful, I think that's projection
Liberals are against all forms oppression except those that they like (speciesism, Russophobia, Slavophobia, Sinophobia).
I say this a lot, but interacting with those people isn't for those people. It's for the passive onlooker. It's well documented that being exposed to the same information/idea repeatedly can make you believe that idea. And apparently (recently learned this) negative gossip can be completely derailed by a single dissenting voice early on in the gossip.
So, if possible (safety, mental health, emotional well being etc. willing) pushing back against these anti-social opinions in public spheres can prevent the spread of them.
Don't give the fascists any platform. Let them know that nowhere is safe for them and their hate.
