There are a lot of women that game, they are not any less capable of it than men. They represent a large enough group for their interests to be recognized and targeted. The absolute male dominance in the industry also suggests that females are very much being excluded from the process. Men aren't going to appeal to people that don't have their interest. Women would better be able to appeal to other women.
This is an issue that sort of cycles back on itself. People say there are not enough women gamers, women are viewed at inferior at games and in the industry (though the original programmers were mostly women, and the very first programmer was a woman,) they aren't hired, they aren't marketed to, and the majority of the male gamer populace (I stress majority, not saying all dudes,) go on about their business, and then get enraged anytime a female gamer speaks out or a game company tries to appeal to female gamers, often accusing them of having an "agenda"
I'll simply say, as someone who went through college with a major in Computer Science, I think there are very few female programmers in general. There were 3 female students in my group of about 40, and they all dropped out within the first year. I know of 2 that actually went and got a degree, one of them a Master's, in the higher years. That's a woefully low number, and chances are none of them went to work in the AAA games industry, as that's not the greatest career path for a programmer in general (I know I'm steering clear of it).
It's not the industry that's excluding them. It's not the school system either. Before college, every maths teacher I had was female, every information science teacher I had was female, and all but one physics teacher I had was female. There was nothing there to discourage them based on their gender. And yet the numbers are what they are.
One thing to consider is though, if the majority of male gamers are silent in the face of this discrimination and outright abuse of female gamers, are they not complicit in the act? By letting this happen, by not ostracizing or speaking out against these men, they are allowing the problem to persist.
BurnedToast, is this an issue for you though? Do you CARE about it? I don't consider rape and murder threats so serious a person has to leave their home or cancel speaking arrangements as just trolls and jerks. It is a dangerous criminal element. What have you, as a male gamer, done to speak out about it? What do you do in the face of sexism amongst your peers? Do you stop it in its tracks or do you remain silent and hope it goes away?
I've never seen anyone abused online based on their gender. If anything, I've seen favoritism in MMOs based on gender of the character a player was sporting (although I've heard this has died down by now).
Also, when rape and murder threats arise, that's when you call the police. If it's a criminal offence and it actually happened, you call the police. They have ways of tracking who did it. You live in a civilized country, call the police. Don't tweet about it to rile up a useless internet mob in outrage. Call the police.
no rape and murder threats, especially anonymous, are not something the police will help you with. It happened, and the police did nothing, they don't even do anything about stalkers, they really don't care if someone is threatening you. They don't have ways of tracking it, and acting like remaining silent is a good idea is WRONG. The fact that you think speaking out about it is stirring the pot, that women should shut up and let the authorities handle it... or what? they are inviting more trouble and now they deserve it? I mean, police don't even actively pursue rape cases when there is evidence, why would they bother with a threat.
The fact is, the first programmers were women, the very first programmer was a woman (though she was waaay before the first computers,) women were crowded out early on. Again you are wrong. The reason you had female math teachers but you saw no female programmers is because teaching is considered an acceptable female profession. But, in general, both sexes perceive women as being inherently worse at math, and after middle school, about the time boys and their opinions start to matter, female math scores drop off. However, there are quite a few female game developers doing indie work, they just don't get into the big games and the big companies.
See this is a big problem. This "I don't see the issue so it doesn't exist" mentality is supporting this kind of degenerate behavior and general sexism.
Let me be the first and probably not the last to tell you that you, as a male, will not see the problem most of the time, you might even overlook it when you see it. As a female, I have had some of the most awful stuff said to me imaginable. I have had people do things for me, and then use that as a way to come on to me, as if I owed them some sort of sexual service, I have watched women get slut shamed for trading pics for in game currency when that is their body and their right to do (it is not the "problem" which you seem to think it is,) I have dealt with girls who had a guy guilt them into sharing pics because he said he had testicular cancer (he didn't and he did it to a lot of girls) then share said pics with everyone. Of course, they got slut shamed, but guys shared dick pics all the time, and no one shamed them. I had a guy intimidate me and frighten me by threatening to do things in game that would destroy my character's reputation (which was already bad as an authoritarian female figure, basically he was going to do something that I would have to kick him out of the city for, and inevitably, because he was a powerhouse pvp'r, everyone would hate me for it,) to get me to share sexual details and pics. I have had guys make nasty comments about my sexual organs because I owned them in pvp, and dear god, I don't dare do voice chat on games like TF2, the creepers come out in force. And I don't dare stream games because that brings them out also.
You have no idea what you are talking about and it behooves you as a gamer who I assume does not approve of this kind of thing to educate yourself to the problem.
