Still difficult to do, for me, since the arguments are based on the platform that games perpetuate sexism and misogyny in the real world. Are there studies that prove or disprove this?
The arguments are not predicated on that at all. It is not a cause-and-effect relationship. Once again, sexism in games is sexism because sexism is perpetrated mostly (though not exclusively) thorough its expression, while violence in games is not violence in the same respect because violence is perpetrated mostly (though not exclusively) through actions.
Lets think about this from another perspective -- imagine we are talking now about billboards rather than about games. If someone put up a sexist billboard, which they are entirely within their rights to do, we would still call it sexism because it is sexism. If someone put up a billboard portraying violence, which would equally be within their rights I suppose, we would say that it is a violent image, and we might say that this crosses a boundary of decency, but we would not say that it is violence.
I am not aware of any studies that prove or disprove a link, but as I have stated for the above reasons, I believe a link to be unnecessary because it is one and the same. What I am certain of, however, is that violence and sexism are different, and so you cannot cite studies that refute a link between media violence and violent behavior in order to imply that the same relationship exists between sexism in media and sexist behavior.
Sadly you can't have a serious discussion about it because Anita, McIntosh, Cross, and the others will label you GG if you disagree with any of their points and block you. They have made it clear they only want to converse with those who agree with their points.
They don't owe everyone and their mothers' a personal conversation -- they have outlets that reach a great number of people, and they do seem more open to discussing those counterpoints in appropriate venues, but they also have a duty to stay on message. This is another smokescreen-style tactic, which basically is making the argument that because they refuse to be distracted to the point of failing to deliver their intended message, that they are unwilling or unable to engage in what their detractors are painting to be a constructive dialog.
Perhaps more importantly, there is no real need for either of them to discuss it because there is no shortage of contrary viewpoints, both well informed and utter bullshit not-so-much. To demand, specifically, they they respond to all general queries that are well-provided-for elsewhere, is to once again make this whole issue about the personalities expressing it, rather than the issue itself.
And once again, making it about personalities rather than issues is predicates all of the smokescreen tactics that are clouding the real issues and any productive dialog. It is not fair to accuse Sarkeesian of not engaging in productive dialog when that is not what is being brought to them 99 times out of 100.
For example, most of McIntosh's tweets come across as implying he is wanting to remove violence in games, but then claims he isn't. So I simply tweeted to McIntosh "Help me understand. Are you & FF calling for the removal of sexism & violence in games?" Simple question to allow him to explain his stance because his tweets seem to contradict themselves. His response was to simply block me from viewing his account rather than actually engage in any form of discussion.
That's a reasonable an honest question. Perhaps he's already addressed it elsewhere, or feels that his stance should be apparent based upon past statements and publications he has made. But again, he doesn't owe you a personal response, and not providing you with one does not mean he is unable or has ulterior motives.
An incredibly plausible explaination is simply that because their communication channels (twitter, blogs, forums, youtube, et al) have been so clogged by detractors (such as from GG) and harassers with a clear agenda that they have decided that the only reasonable policy to achieve clear lines of communication with those who care to hear from them is to ignore or block anyone who appears to be agenda driven. Its easy to lay the blame on them, but its really the unproductive and harassing attention that's been so disproportionately brought against them that could be to blame. Perhaps if they did not have such a volume of utter bullshit "honest questions" to sort through, they could be more discriminant and answer more, you know, honest questions -- like yours.
That you have been blocked is indeed an undesirable outcome, but consider the experiences they have likely had in the past -- Instead of this exchange: "Hi! What about X?", "Well, we at W think Y about X, because Z", "Oh! I guess I agree/disagree, thanks for explaining!" -- that one initial question, when presented from someone with an agenda might have exploded into 10 or 100 tweets in which the asker then tries to win a war of words and attrition by responding with pedantry and non-sequiters about Z and mostly W, but rarely about X or Y. But once again, its not about you personally, or even about McIntosh (who certainly has at least one assistant to help wade through the noise), but about a policy likely designed to aggressively preserve what signal they have.
This is all I want, to know that the devs are choosing of their own free will to make the games represent women better and not because critics and journalists are pressuring them into changing them.
Look, I'm concerned -- we're all concerned -- that games remain a viable medium for artistic expression. I'm very wary of the slippery slope, myself, and believe that we do not ever want to give any entity the power to determine what is art, deserving of protection, and what is lesser-art, not deserving of the same protections, or is perhaps not art at all. To do so would invite censorship of the worst form.
But criticism is not censorship. Criticism is the impetus for change, not its enforcement. To make criticism so bound in a legalistic view of what responses its contradictors are owed, or to make the act of levying criticism so uncomfortable that most would be loath to undertake it, or to make it carry the threat of violence being visited upon you, now THAT is censorship for all intents and purposes. Not all of their detractors want to achieve that, but a minority do, and a substantial portion of what remains tacitly approves or at least does not expend significant effort rebuking it. Of course, they do not and should not have to spend energies going off-message in this way, just as Sarkeesian is not obliged to go off-message to respond to every criticism personally.
If they are critical, and others are anti-critical, and if that causes designers, studios, and publishers to start thinking about how they can make female characters that appeal to more than the tits-n-ass, machismo crowd, and causes consumers to at least take notice of the male chauvinism they are being spoon-fed, then that's precisely all that they have wanted to achieve as far as I can tell.
