Try reading Tara Tiger Brown's piece I referenced above. She does mention fake geeks, but c'mon, context. She's writing to women, for women, and about women. Of course she doesn't mention that.
And it amazes me how quick people were to throw Tara Brown under the bus. I mean...sheesh...how dare she say such horribly sexist things???!? She's telling people she doesn't see as geeks to go away??? Who is a tech writer who writes about women's issues in tech for a major publication who helped found LA Makerspace to decide what is geeky or not? Throw her in a refrigerator and throw the refrigerator under the bus, that horrible woman!
Seeing the problem yet?
She references Patton Oswalt's piece Wake Up, Geek Culture. Time to Die, to her credit That's a good one to read, too, and doesn't focus on women. I happen to agree with him. I mean, for Pete's sake, people who like Star Wars think they're geeks now.
To get back on topic, though, I see it as especially egregious that these women featured here have to defend their geekiness. I think having the brain power to write software for a particle accelerator should earn some respect, and I don't see why anyone would think that being into Lord of the Rings is something someone would do just to attract the guys. And like Patton Oswalt, I don't understand why liking "nerdy" things should make one a geek. I mean, my wife is a lot more socially active than I am, and yet she caught more inaccuracies in The Hobbit: An Unexpected Journey than I did. I don't see her as particularly geeky, but then I remember a time when that was an insult, a word chosen because of circus geek, as in you were some sort of freak not worthy of regular society, so it's not a label I'd choose for myself, let alone her.
