Sometimes I really wonder what the crowd I interact with here on HN is really like. Are they true tech intellectuals, or are they people who wouldn't hesitate to hurl racial slurs if there wasn't the threat of being banned or flagged.
I'm not trying to be mean when I say this: don't kid yourself into thinking you're in a club with the cream of the crop, anywhere - you're just setting yourself up for disappointment in the best case and horror in the worst case.
Needless to say, even "intellectuals" can be racist.
Not "even" intellectuals. Eugenics and racial superiority were progressive intellectual concepts less than 100 years ago, with people writing self-important letters to each other about it.
