let me know what industry you work in where you can poison the well so badly and not get canned.

Policies that are effectively affirmative action are by definition lowering the bar for diversity candidates. His statement that it can lower the bar is correct but still not something people like to be reminded of. Google (and others) not recognizing this distinction and treating his lack of discretion as hate speech is irrational mob PC rule or just plain cowardice (if he was fired for PR reasons).

In an n-dimensional space where we take into account all the factors that go into whether or not a candidate is given an offer, you're actually complaining about "lowering the bar" when the bar is already lower for people (for people that's not being targeted for affirmative action) due to systemic effects? You're actually complaining that we're lowering the bar by tweaking other variable so that the bar will be effectively the same obstacle for everyone?

Please explain your rationale for doing so.

Or sued, seems like this would be an easy basis for a hostile work suit. Couple promotion denials, a documented complaint and this manifesto would probably be an easy lawsuit, though INAL.
