It's important to distinguish between what the memo's author says, and what effect his words actually have. It
is an anti-diversity memo, even if it isn't intended as one.
The author makes shaky statements about gender, reinforcing sexist stereotypes. The author applies rationalist disclaimers, which enables already-sexist readers to feel that their sexism is rational. And, most distressingly, the author asserts that Google made a mistake hiring many of the women who work there. Actively making your minority coworkers feel unwelcome is an anti-diversity behavior, and it was an obvious and predictable consequence of how he chose to communicate.
I don't claim to know the author's intent, or how he truly feels about the women he works with. But, regardless of whether he's actually opposed to diversity, we judge words by their consequences. These words are thoroughly anti-diversity in consequence, and judging them in a vacuum is dangerously naive.
