I personally don't care if any girls want to be a part of the (whatever) culture we have, I love being around the opposite sex. But I would appreciate it if they are sincere. I don't think geek checking is something that should be done to people because you'll just come off as a rude twit. People don't like fake people anywhere, why would they be tolerated here anymore than any place else?
Of my own personal experience, I had a small group of friends that I played SWTOR with (yea i know..) and a few of them played warhammer/D&D and some played magic, so we'd all sometimes sit in the college lounge or the hallway between classes and shoot the shit about whatever nerdy thing we were doing. Some of us had friends outside that circle, some did not. Of the ones that did (myself included) had some pretty attractive female friends that would always mock us for talking about whatever nerdy thing was happening that day. Generally it didn't bother me or my other friend, but to some of them it did, and they even approached me about it personally saying they didn't want attention drawn to themselves to get made fun of and mocked. So I relented and shut up when they wanted me to. But a few times some of the girls (they happened to be the more attractive ones..so make of that what you will) actually said some really nasty things and even told us to take our (obviously beneath them) conversation somewhere else, this really rubbed me the wrong way so I put them in their place. This has been common in my experience with most females regarding gaming/nerd culture. Many dabble with CoD and Mario. Angry birds, mobile games, and classic arcade Nintendo stuff. But that is as far as they go. I've recently been in a server VOIP for my Guild Wars 2 realm for its open world PvP, and there are lots of different personalities there. It is predominantly guys, but there quite a few girls there too. But most of the girls don't seem like they are there to play serious PvP or PVE. Many are there being chatterboxes and trying to draw attention to themselves, the worst of which are drama firestarters that won't get muted or banned because some have sexy voices and in a channel full of 60 dudes and 2 or 3 girls, some guys are gonna want to hear that. If I bear any animosity toward women or fellow male gamers it is this, play the game for what it is and enjoy it. Don't use it as a tool or vehicle to achieve a different end like starting drama. Being a nerd/geek is very much steeped in enjoying something for the sake of itself and nothing else, it comes from deep immersion and giving yourself to a certain aspect of the culture and enjoying the hell out of it. It is much the same as sports in this way for sports nerds.
Not all women are drama seekers out to get attention, and I would be foolish to label them as such. Like anything else it is the few that spoil it for the many, and by reading this thread it seems there are many female gamers out there that would be an absolute JOY to play with. Anyone who wants to experience this wonderful aspect of technological culture I welcome you with open arms. Just please enjoy it for what it is, don't come here expecting to use it for some other means, especially if it is destructive.
PS. Most peoples ability/desire to delve so deeply into a culture might not be the same as your own, that said our gamer culture is still male dominated. That is why finding a woman like in this video should be considered a mythic/legendary accomplishment
