He concedes the very point you mention here. That there are _real_ historical biases that should be corrected and removed. From the memo: I hope it’s clear that I'm not saying that diversity is bad, that Google or society is 100% fair, that we shouldn't try to correct for existing biases, or that minorities have the same experience of those in the majority. He's saying that the inability to get to a 50/50% split on gender lines may be unrealistic. He makes no comment on if the 20/80 split that currently exists is fair or not. Just because he doesn't go into the history of all bias that did exist in the past, doesn't mean he discounts it and unworthy to be addressed. Further, at what point does a society atone for past biases? If you are even trying to correct the injustice in the past, should you not have an idea on what normalization might be like? Perhaps and this is his question, an exact 50/50 is not what a idealistic lack of bias would create in the first place. And the thesis is that it would not be created in that fashion because women self-select to enter different professions for biologically based reasons. Now all those items might be false - its a hypothesis, not a universal truth - but it appears the research from social psychologists backs up his claims as valid. Now perhaps they still want to argue between themselves, and fine I'm ok with that go for it - but it appears he's done with with good faith. And even if you think his arguments are poor, or he's naive, or anything else, that's fine too. The problem is - and this is where my main issue and the root of all of this - is that he should not have been fired for this. This appears to be a betrayal of liberal free speech values that many people claim to support.
