My youthful experience was that nerds tended to be just as sexually active as jocks. They just tended to be active in different ways.
(And on the flip side, I know a few programmers who are incredibly nice and patient people but still have problems talking to girls. So I'm not denying that some guys find girls intimidating. But I think that inexperience isn't necessarily what leads to poor social skills in other areas.)
I don't associate with many geekier types of people, despite a lot of overlapping interests, for precisely this reason. I'm very sensitive and easily hurt/annoyed by that kind of behavior. So I avoid a lot of things that I'm actively interested in because the crowd is so abominable. The gaming world in particular; I don't even look at games which draw is online play, because I've never found an online gaming community that I've felt comfortable being a part of.
Basically I don't hold with the notion that there is a gang of males deliberately driving women away from tech.
The argument isn't whether or not some people, including many women, are turned off by the current culture of programming. They absolutely are. The argument is whether it's the responsibility of the current culture to try and adjust its ways to let more people in, or if it's okay to let it stay the way it is. People in this thread are making arguments for each side.
After the government forces them to prove they're not pedophiles, of course. Say what you like about the software industry, we don't have ritual humiliation baked into law.
