Males, sure, there way more men than women in dev roles.
At least for Silicon Valley though, white people are, oddly enough, underrepresented relative to the US as a whole. Though that's less because white people are discriminated against, and more because there are a LOT of Asian immigrant tech workers.
That’s what I was literally taught in school. Our required anti-racism lecture in jr high explicitly said that only white people can be racist and only males can be sexist because only they have power.
I understand the point of the argument; systemic oppression comes from power. The argument just seemed odd though.
There are people alive today who's parents or grandparents lived for a time without civil rights. I don't think disregarding their experience is the correct direction to take.
It looks like you've crossed into using HN primarily for political and ideological battle. That destroys the spirit of curiosity that HN exists for, and is against the site guidelines. Ditto for comments that cross into being nasty, like https://news.ycombinator.com/item?id=20942577 and https://news.ycombinator.com/item?id=21128710 and, unfortunately, others you've posted.
The California legislature (for example) is less than half white.[1]
You could argue white males are overrepresented in some circumstances, but claiming white males hold institutional power exclusively (which is what you inferred) is just plain wrong.
