For anyone who hasn't read the actual memo yet, what he did say was "Hiring practices which can effectively lower the bar for “diversity” candidates by decreasing the false negative rate". That's not anywhere near "a large number of his colleagues were not adequate to be his colleagues" or "were only hired because they had the right genitalia". All it means is that a larger share of qualified white/asian/indian male candidates get rejected, compared to qualified diversity candidates. Anyone claiming otherwise is blinded by outrage.
