These early social influences are a very significant part of the whole diversity/discrimination story and of what the diversity policies are trying to solve. The best ways to improve diversity and fix gender biases are still ‘debatable’. But speaking about the ‘memo’, this particular document is incorrect to the level it doesn’t deserve the debate. Despite the author claimed he created it “all in the name of open discussion”, he mainly created a hostile environment for his coworkers, which is unacceptable (and the fact he didn’t even understand that doesn’t excuse him). I agree with this comment on the ‘memo’ story, which is by far the most sane one: https://medium.com/@yonatanzunger/so-about-this-googlers-man...
Men are underrepresented in certain professions for sure (and it is a part of the diversity problem), but the current discussion is about underrepresentation in tech, and white men are definitely not the main subject to it (so I don't see any double standards here).
