Liberals today: "Embrace diversity of thought, color, and sexual genitalia! Wait I don't like that thing he said, fire him. Wait, he's mentally ill and thus persecuted, he needs to be protected. Wait, autism isn't a metal illness, he's fine just the way he is. Wait, he's a white male, he's not fine just the way he is, he's evil. Wait, he's self-identifying as autistic, he's not really autistic, a doctor has to diagnose him. Wait, no, that's different than self-identifying your gender, that's totally fine."
He went out of his way to praise women engineers and to emphasize he supports diversity.
There are just certain that intolerant people cannot discuss rationally, like biological gender differences.
The fault lies with the intolerant minds, not Damore's approach.
If we forget this, then intolerant minds will have awesome veto powers over what the rest of us will be allowed to discuss.
Intolerant people are likely to use those veto powers.
That was when there were some low thousands of software engineers in total. Hardly statistically significant to compare with today's population.
The first few engineers were female because of sexism in the 1970s. The only mainstream jobs they were allowed to have were teaching and programming. There are fewer females now because of lack of sexism not due to it. As society became liberal, women started becoming doctors and lawyers, which matches with their interests much more than programming.
