The ONLINE gaming community is sexist. (Well I mean the Japanese developers totally are too haha. Such as making lightning's boobs bigger in LR just cause they wanted them bigger, Or making Quiet have a plot point to wear skimpy clothes because that makes it better lol, but that's a whole other topic entirely.)

Not like online gaming but the communities online. Places where you can find a similar opinion and then it becomes reinforced via echo chamber. It's what happens on Reddit. It's what happens on Tumblr. It's what happens on twitter. Etc etc.

It happens with political ideologies (never look into yahoo comments, good god.) or music opinions, video games, whatever. This isn't the representation of the whole group, but just what is dominating online discussions. Occasionally you'll run into it in the real world but that is just one person versus however many you've met.
