You're missing the point that there is a positive feedback loop at the source of the problem. The reason that women (or minorities for that matter) don't get into some fields of STEM is because there are no role models that tell them it's a good idea to do so. So there is a chicken and egg problem, and the only way do break the cycle is to give priority to such minorities. Is it fair to the members of the majority? Perhaps not. But in the end, I believe, it will justify the investment. Consider it a small price to pay for the millennia of oppression.
No there isn't positive feedback loop at the source problem and no giving priority to minorities does not make any sense. You don't have to. There is enough fight over the talent that anyone who actually has talent will get a job.
Having worked in tech for 20 years and hired and fired all sorts of people I am unconvinced there is a problem in tech as big as it's being claimed.
The idea that you can only have role models if they are your gender is really really absurd and if people are really falling for that then they have a problem not the tech-scene.
There is no actual evidence that diversity in gender does anything for a company besides creating more complex work environments. There are far more important types of diversity to strive for.
