The thing is, the guy wrote what many people think - outside of tech. It just so happens that techies happen to be very open oftentimes.
I mean, what this person wrote, I heard it on various occasions in different formulations from various people. Even a woman (a Psychologist student at that time) once told me she'd rather have a male dentist and a male president.
I imagine tech industry to be brutal for woman, but so are probably a lot of other areas like construction works, virtually anything with hand-labour involved, not to speak about the military.
Anyways, it's great that people in the tech industry speak what they think. Maybe things change faster this way.
