I used to be in quite a few elevator community servers, but then they all started ranting about how (back in the day) I made it public on there that I was pro-CPC, and then someone brought the whole CPC drama back up again and then everyone started hating on me because I supported the CPC. Someone even called me a “Russia supporter” despite the fact that I don’t support Russia and I support peace between Russia and Ukraine and then he got mad at me for not supporting Ukraine. And he also played the “tfp bad cuz he support ccp” card.
Anti-communism is not a particularity of communities of people who enjoy recording elevators. Communists in the west are a tiny minority against a much larger bulk of society that opposes them, and this proportion is most likely to be reproduced inside groups dedicated to activities with little relation to anything that evokes political thought.
