Now see, there's a flip side as well, for some men (I'm usually included in this). If there's a debate on sexism or the like, some men refuse to comment or talk at all, for fear of being demonized. I only really participate in discussion on GAF because I know I'm not going to get killed for my opinion, so long as I'm concise, polite, and reasonable. Many men, instead of discussing, withdraw.
While this topic is primarily "harassment of women in the video game industry" its a much broader problem, and I think its one that has to be met with a push from both genders, on multiple fronts. Instead of framing the argument "Men, stop being sexist!", it would be better framed as "Everyone, stop being sexist!" otherwise it comes across as a direct attack on a single gender. Instead of working to alleviate issues that hurt both genders (maybe one moreso than the other), its immediately turned into an adversarial affair.
I guess the thing is, we need to address the problem, unilaterally. The number of times I've seen a guy call out another guy for calling someone a "fag" has been quite a few. Conversely, the number of times I've seen a woman laugh and mock someone after seeing the above scenario are more than I would like.
