I think I can count on one hand the amount of times those topics are brought up about China in good faith. Maybe you've seen it more often and seen the brigades more than me
My thing is, why is it always China lol. No one comes into these spaces with scorching hot takes about the LGBTQ rights in Laos or the economic systems of Cuba. It's a lot of CHINA CHINA CHINA, which between the current culture, and trying to deprogram baby leftists, it's really hard to spot good faith discussions/let them grow. And the thing that really sucks is every good China discussion is like 1 rogue comment away from name calling, it's hard to stay on track
