When did I say that I want to be able to use differences between men and women to discriminate?
I said that hiring on diversity over merit was wrong. That's it... I never said anything about sex in terms of merit. The only place any discussion of sex or diversity belongs is in terms of messaging and in terms of possibly promoting jobs that are disproportionate to natural propensity towards a given role.
If you can't discuss, review, document, test or otherwise examine bias in terms of nature, environment, upbringing, educational exposure and other factors, then you can't force equilibrium at the end of a long process.
You can't hire 50% women in an industry, where only 20% of those educated for that field are women. Also, so long as choosing a field of study or work is voluntary, the best you can do is maybe have a more fair representation of a given gender in a given field that doesn't show only above average looking women wearing glasses with a few geeky quirks, then relegate them to more personality quirks, or make them less capable over time.
And MAYBE it's okay to have a field where most of the people in that field are of a given sex. I don't see the SJWs trying to get women into garbage collection, or throwing a fit over the gender bias in nursing.
