If some women feel that way anyway, are you suggesting that making more people feel that way helps or makes it not sexist?
Tech pushes many people out, male and female. Even if the men in tech are the same, what about the men who would like to be in tech but were pushed out? Or are all men the same?
I'd wager most men "pushed out" of tech weren't fleeing sexism and gender-based isolation. This whole thing seems like looking at a team of 10 -- nine men and one woman -- and, when the woman says, "Gee, it'd be nice to have another woman to talk to," responding by saying "Well how about you just talk to us nine guys instead? Wouldn't that be just as good?"
