Seriously, everything works out better for everyone in the long run if you value women as people first and foremost. Admittedly doing so reduces your opportunities to make passes at uninterested women. But it significantly improves your odds of success if you do make a pass, and greatly improves your odds of eventually winding up in a decent relationship.
If anything, guys in tech -- the real techies, that is -- are so horribly bad at talking to women that it's being viewed as an alien from outer space that's offputting, not being viewed as a pair of walking boobs. On that note, I definitely agree with valuing women as people. But in my experience, at least, male attitudes towards women in tech as sexual objects are not even remotely a factor. However, the concern that you won't even meet nerdy women if there aren't any women involved in tech is still valid, IMO!
If you wish to continue not experiencing it, then there are quite a few men I recommend not getting to know, starting with Eric Raymond.
If so, it might provide a useful means of distinguishing between the 'Roissy theory' (women are intolerant of low status men) I described downthread and scott_s's alternative theory (women don't want low status for themselves).
And yes, there is evidence that many women avoid strongly male-dominated environments. For some of that evidence look at the article that started this discussion: http://scicom.ucsc.edu/SciNotes/0901/pages/geeks/geeks.html
If you had asked, 40 years ago, "why is the lack of women in math, science, medicine, academia, and leadership positions a problem" this would be more obvious. Since many fields today are more equitable, it is a lot less problematic, although perhaps not for a few folks here and there.
