I'm putting this in LGBTQ as a proxy for action for Social Progressivism in general.
From the post:
We have been contacted by the admins. It is necessary that we request you tone back your language and make a shift away from certain types of memes. It is necessary for the survival of the subreddit and preservation of our culture open to all funny colors.
Edit: This mostly is nothing new, this is simply a reminder that rule 3 exists due to continuing rule breaking content and a warning from admins
They put 2 lists in the main post and pinned comment respectively listing the various slurs or bigoted insinuations PCM users will "result in removals or possibly a ban", featuring basically every type of bigotry except misogyny and anti-native prejudice, with anti-ziganism only being implied in the main post. I think everyone who's known about PCM for more than 2 months will agree little will change (it's been too late for that for at least 2 years now), but I figured I'd put this here anyway.
Didn't watch the video, but going by the thumbnail, "not leaving your least developed areas/poorest people behind to suffer" is nowhere near Communism. Any Social Democrat can do that, hell, Joe Biden can do that.
