I was aware of this problem. I heard about it last rearing its ugly head in Mass Effect 3.
If I might lend my analysis: the Internet has been great for turbocharging the large multi-armed thing that constitutes 'viewer entitlement' that's been known about since long before there was an Internet. The idea that everything out there is 'for me.' For a brief explanation: look at the trend of making fun of the TWILIGHT series of books/films. Most of the people making fun of it are NOT the target audience -- not women with a specific set of fetishes. What doesn't occur to these people is that TWILIGHT is not for them, it's for the target audience. They should not be offended that it didn't meet their expectations, they should learn to do some research so that they don't see movies that they won't like. But the viewer entitlement is there, deleting the 'I should do research' command line and replacing it with 'Be a hate-spewing spigot of ignorance and contempt.'
What does this have to do with 'fake nerd girls?' Well, people are starting to become aware of viewer entitlement as a concept, and once they know it drives advertising dollars, it shakes them out of the experience. Finding someone who shares your interests is a great joy, and if you might some day theoretically reach a level of intimacy with them beyond mutual interest, that's great, too. But one thing I know no human being on the world has patience for is wasting time and looking a fool doing it. The fear, and the word 'fear' is very important in this context, is that these fake nerd girls are wasting the 'true gamer's' time with false hope and insincere implications. Not unlike the 'booth babe' problem mentioned some weeks ago.
People are okay with being deceived, but it must be done with some effort and style. As Lewis Black said, 'You've got to lie to me better than that.' A product or service is nothing if not a reflection of the person who uses/experiences it. I expect some deception and pandering in anything I consume -- they must compete, free market and all that -- but too much and I get angry. Some people (the problem causers of this discussion, they who persecute and scrutinize women in this medium) are so afraid of being made to feel a fool that they will take their claws out if they even suspect perfidy. And that's the problem -- knee-jerk hate reactions instead of careful scrutiny.
Jim, as usual, cuts to the heart of the matter quickly -- if you don't like it, stop looking at it. The attention-grubbers you fear wilt if not fed, and you are feeding them almost constantly with your shotgun approach of painting all women with the same brush. It's unfair, counterproductive, and makes both of us look stupid.
What I don't understand is people who keep on being assholes after they find a woman has the chops to back up her claims. Why is the response not then delight? It took me a while, but I think I've sussed out the answer: it's still a perceived insult, because they were wrong about something. And no one likes being wrong. Could ya be more selfish? You bluffed and were called, deal with it. The world doesn't need to conform to your bruised ego.
