Well, guess what? pg is his own person. He's just a guy who invests in startups, not some sort of idol upon whom you can project all your transformational, social-justice dreams for the tech industry.
Is there racism and sexism in tech? Sure. Is that pg's fault? No. Has he done things to mitigate this? Sure. Are the "social justice jihadis" appreciative of this? No.
The cashier at the local taco shop speaks to people in Spanish or English depending on whether or not they look Mexican. Is that a problem? I don't think so.
Let's say you give a Hindi greeting to an Indian guy who's second-generation American and doesn't speak Hindi. What's the worst that can happen? Well, if he's a SJW he'll spread your name on the internet as a "racist asshole". But if he's a normal person, you get past the misunderstanding quickly, and plus he knows that you know enough about his culture to have learned its language, and he might even appreciate that.
Our primate relatives are racist and sexist. What makes us think that we can not be?
Pretending to ignore race/sex differences out of some misguided attempt to be polite or "color blind" or "culturally neutral" does no one any good.
By "racist", I mean "actually despises others because of their ethnic background", not "has the odd awkward or confusing moment of ethnic / cultural misunderstanding".
Similarly, by "sexist", I mean "actually dislikes or has contempt for the opposite sex".
Of course the bar for these words has been raised to the point where the political Left can call someone a racist because they do not support a specific affirmative action policy, or a sexist because they disbelieve certain cooked-up statistics about the alleged "pay gap" between men and women.
I don't think we can assume that is the case if we are using the "power + prejudice" definition of racist or sexist. As far as I can tell, this is the prefered definition of racist and sexist among social justice warriors. If to be racist you must be prejudiced and have power over those that you are prejudiced against, then there are some people who literally cannot be racist.
Typically this definition seems to only be used to shield SJWs from 'friendly fire'.
