The most toxic communities I know of are the Genshin community, Payday 2, FFXIV and source games communities in general.
What I think is weird about folks hatin on the Genshin Community is it’s essentially a single player game. There is no community really outside of social media. I would say social media is the problem.
This! I’ve always had super friendly interactions with Genshin co-op, even when searching through the co-op tab rather than looking online (aside from one kid I had to kick because I was not going to buy them a welkin lol). The only time I’ve come across problematic behavior is through social media. It’s also very popular so of course on twitter and reddit there is going to be a large loud volume of immature people, but that’s most games. In game people are usually good.
even around the game people are good provided you aren’t broadly exposed to it via tiktok/twitter/reddit/twitch. Some of the smaller genshin discords have been really helpful and sweet and full of good people. But honestly I think there’s just a critical mass where communities like that kinda blow up so that’s not a genshin problem so much as that’s a “so many people in one place at one time” kind of problem lol
