It's not a non sequitur, by "discrimination" I mean unjustified discrimination. I didn't "twist words", so stop making bad-faith accusations. You have setup a strawman of your own, deciding that by "face no discrimination" I must mean an extreme level of literally no negative bias, even at random or by error.

I disagree that "Making it proportional is [a target]". Hiring should not be based on sex/race, but that doesn't mean it can't be based, justifiably, on things that correlate with sex/race. The issue is here is that there is no direct insight into the factors hiring decisions, other than broad hiring statistics than do not distinguish between e.g correlation and cause.
