Gamers have their clans too and people can get kicked from that. You can get mic banned or worse too for being too flagrant. You can lose real money if microsoft bans you and you had a bunch of digital games for example. In sports its not like all the interactions are going to be moderated either. Sports are pretty notorious for talking crap about the opposition, but it can get much worse than just talking crap. I heard a lot of terrible racist things too during my time in high school sports just 10 years ago, from players and parents. There are a lot of nasty people out there and they perpetuate those views on their kids.
