I can't disagree more strongly with the things you wrote. In fact, I'm pretty appalled by them.
"Men who go into technical fields suffer serious scars from social rejection that's every bit as painful as apartheid."
I'm not really sure you get what apartheid is.
"[A] woman is pretty presumptuous to think she will be treated fairly by technically oriented men"
Why? Why is a woman, just because she's a woman, supposed to be treated unfairly? Just because some people were treated badly (supposedly) by other women? That's just... random. If I were treated badly by a blond person once, or even more times, that wouldn't make it OK for me to treat blonds badly, just because they're blond.
On top of these points, you're also implying a lot of things that aren't true.
"Men who go into technical fields suffer serious scars from social rejection"
All men? Only in technical professions? Why are you giving weight to this not very accurate representations of anyone going into a technical career being socially scarred? Even if it has some basis in fact, it's nowhere near ubiquitous. And it's certainly not only people in technical professions - many people have scars from childhood.
Besides, you're making it seem like the women are the problem, who "socially scar" and "completely shut out and exclude" technically-oriented men. In truth, it's often the men's fault. They just don't put as much effort into "socializing" that they do into other things. It might not always be conscious, but it's a choice they make. The worst thing to do is to "blame the women", both because it's inaccurate, and because it's unproductive.
