So I don't mind that much when people start flaming with words like noob, scrub, you suck etc. I mean, that's unpleasant and unnecessary and that person is an asshole. It serves no purpose. But racist, transphobic and misogynistic behaviour crosses the line. Also those "kill yourself" "I hope you get cancer" etc. remarks. And behaviour like this should be punished by the devs. And people who get so riled up in a game, or get some kind of satisfaction from this should get help. It's not normal and healthy behaviour.
I don't really understand why this gets so much defense and downplaying here. Can't think anything but it's those people who partake in this themselves. And just because it happens often and has happened for a long time, doesn't mean it's okay. More like it's finally time to do something about it. If you aren't bothered by it, then good for you. But don't think that nobody else should be.
