Lets not pretend that there arent fake geeks, girls and guys.

Everyone has something that they're passionate (or geeky) about, honestly. Whether it's video games or books or shoes and make-up. Now people who are like "omg I was on facebook for three hours straight last night I'm such a nerd lol" are annoying but don't judge someone if they call themselves a nerd but don't look the part. Most people who are labeled as "fake geeks" are the ones who are new to something and really want to learn about it, and it's terms like this that drive them away. Everyone expects them to be experts at everything right off the bat, and if they slip up, they're suddenly fake. 

In terms of actual sexism in nerdery, I haven't come across any in my community. If anything, it kind of feels the opposite. I'm the only female in my computer engineering class and some profs will correct themselves because I am there. Like, "okay guys-no wait guys and girls". It's really awkward and I wish they wouldn't do it.
