There's a set few countries where if you post anything not explicitly negative about them, people come out of the wood works to post a few set phrases.

here's a submission on the frontpage right now https://www.reddit.com/r/iamatotalpieceofshit/comments/snzur..., particularly look at some completely benign comments getting buried with downvotes, you basically have to preface everything with "I hate the chinese government, but" or else you get called a chinese shill and downvoted.

edit: like look at this https://www.reddit.com/r/iamatotalpieceofshit/comments/snzur..., this dude is literally copy and pasting this comment and getting 5000 upvotes and awards for it and all the responses are basically "i haven't watched any of this but all chinese are cheaters by blood so you're definitely right" and all the responses to those are "you will lose social credit" or "winnie the pooh" or talking about chinese shills despite every copy and pasted anti china post having positive votes, its so weird.

it makes me mad that these huge internet communities that are and have always been racist against chinese people (i.e the brainwashed, cheaters, drones rhetoric that has existed since 2013 and almost certainly before) but now they use tragic humanitarian crises as cover to shut down all pushback. reddit discussion on the olympics is literally more racist than what gets posted on /sp/, and is far less self aware.
