There are trolls and haters who take things too far.
It's okay to troll sometimes, and I find it funny sometimes. But I've seen some trolls take things too far to the point they offend people who did nothing wrong. Sometimes they even harass users from communities to no end. And sometimes they make memes about hating on a community so much that it's all that they talk about and meme about.
There's this YouTuber whose content I always watch and enjoy, Acheeto, he said that if stan means stalker fan, there should also be a thing called stater, a stalker hater. While the stans make their entire personality about loving a certain person or group, staters make their entire personality around hating a certain person or group. And both are unhealthy.
