Just the assumptions that the difference in numbers is because of discrimination is wrong, or at least the numbers alone don't prove it.
It could prove the opposite thing: that men are in a bad position because they are forced to study hard and lonely subjects. (Not saying it does, just saying the numbers could be interpreted in any number of ways).
I didn't say it was discrimination, and I've never felt like it was. But I'd feel uncomfortable if I went to a conference that was basically held in a strip club. I even felt a little uncomfortable at Google's Christmas party in 2004 when they had scantily clad Go Go dancers on tables everywhere.
But working often with people that have exceedingly poor social skills around women is something that has affected my job satisfaction. I'm sure men have other things that affect them that I haven't had to experience though.
I wouldn't like strippers at a conference either, no question. I haven't really experienced above average social incompetence around women in IT, but as I said elsewhere, there tend to be not many women around to act incompetent with.
Of course I would like to have more female coworkers. I just don't think that go go dancers in Taiwan are the root cause for not many women being in IT.
