Then call out the ones you know for a fact are assholes and racists, and stop adding to the problem by whitewashing and excusing and carrying their water.
I personally know LOTS of brilliant people in the bay area tech scene who are not assholes, and are wonderful kind people, so if you only know assholes, you're hanging out with and licking the boots of the wrong people, and that's your problem, and you should re-think who your friends and heros are.
