Because anecdotes aren't data? This is a site aimed at hackers and programmers and you really think the utterly thoughtless logic underlying your post passes muster?
I'm a gamer. I'm in a guild. We have female members. We all, regardless of gender, have at some point been the target of idiots trying to bully. While it is impossible to deny the existence of the cesspit, I take umbrage at it being perceived as the majority of we gamers. It is a problem, yes. But please don't lump me and my entire guild into the same bucket.
We have such members. We expect them to abide by our clearly written community standards. We are gamers. They are gamers. We act as a community, which involves not leaving everyone to fend for themselves as an individual.
"The gaming world is a cesspit of maladjusted, comically aggressive, emotionally (and maybe actually) adolescent males"
Sure, the preceding paragraph makes a pass at placing this in context, but this is clearly baiting language. And the problem is apparently so bad that OP doesn't want to even be called a gamer, lest he be lumped in with this cesspit.
Again. For the record. I am a gamer. I'm a lot of other things, too. But I'm a gamer, and so are my slightly maladjusted male and female compatriot guildmates.
The biggest problem I see here is parents letting children play M-rated games. Anecdotally, and with no facts whatsoever to support my theory, I believe this would remove 90% of the problem.
