Behind every person who goes to an interview there's whole life, and every interviewer has so much more information about that person than just her being a female or black. Pretending that by knowing only 1 piece of information, you know they made a mistake, when they clearly have so much more information than you, calling it bias or whatever, is insult to their intelligence. Who the hell are you to know they made a mistake, when you literally know nothing except one little piece of a giant puzzle?!
It also goes for women / black people who didn't choose a career in tech. There are people behind these decisions. They have freedom and free will. You can't just pretend that they are all stupid and don't know what's good for them.
Role model nonsense is even more absurd, because it already assumes things like women can't have men role models. You need to have the sexist mindset in the first place for this to even be a problem.
The whole diversity conversation reeks of so many self-contradictions and fighting windmills, but the defining feature is envy. envy for people who succeeded. and a deep need to excuse their failure with someone else.
