I'm sorry, but anti-white racism and anti-male sexism aren't real things. Sexism is clearly a thing, as shown by your very sexist comment. Stop making HN an unsafe place for women.
The same "facts" could have been stated in a very different way. For example, I could tell the story like this:
"An employee complained about sexual harassment at Github. The confirmation of some of her accusations by an independent investigator led the CEO to step down."
The only references to sexual harrasment I found in OPs post was:
> She accused the company of sexism and sexual harassment (independent investigator found none, and other female Github engineers said there was nothing wrong)
> JAH also complained of terrible sexual harassment - that is, men looking at women spinning hula hoops. Women did not complain, but JAH got offended on their behalf anyway.
Are these not facts? Were "men looking at women spinning hula hoops" and this other individual brought it to someone's attention as sexual harassment?

Even by the narrow "power plus prejudice" definition this is false; this is pretty readily observable, in the first instance, in lots of contexts where whites are not in a position of power (even in localized contexts embedded in broader societies where whites are in a position of power.)
They may be less significant in modern American society because of the general power distribution in the overall society and therefore the most common power distribution in particular contexts embedded within that society, but that's very different than not being real things.
There's no anti-white racial oppression going on (in the US; may differ by region). There may be instances of anti-white racial discrimination.
There's no anti-male sexist oppression going. There may be instances of anti-male sexist discrimination (eg. assuming that male kindergarten teachers are child molesters).
Two different definitions of sexism and racism.
Depending on the definition of racism and sexism, the "anti-white" and "anti-male" variants may exist or not. Please don't assume that your definition (which seems to be of the "oppression" kind) is universal.
