I mean, most of the policing I see from people aren't even racist, sexist or homophobic, it's just banter or light hearted commentary.
Comment "Oh ninja, when will you learn that orange candies aren't your friends? :P" after they die the 3rd time and they get super aggressive.
Mention "Hey tank, mind using some cooldowns on wall to walls a bit more?

" and all of a sudden you get backlashed at for "telling them how to play".
It's like people can't take *ANY* criticism nowadays when you could comment on this and people would shrug it off, laugh it off or play silly back with you, but like I said. The online community has definetly changed over the past decade.
