No, but you can start conversations and learn by asking questions. What silences conversations and prevents learning is a menacing attitude towards to having conversations and asking questions.
He was attacking core assumptions about what a fair society should look like.
Aren't the assumptions the very things which should be questioned? If your axioms are flawed, then the systems built upon them are invalidated. Why should there be equality of outcomes? Should Asians have representation in the NBA proportional to their population percentage? Why is it that Jewish people have been radically more successful than the general population at tailoring across literally thousands of years of history, in so many different cultures and contexts? Why is there a Scandinavian Gender Equality paradox?

(Watch that video and try and tell me that the "equalists" don't come across as unreasonable, closed minded, and ideologically driven?)
A broad reading of history tells us that cultural human capital is tremendously powerful. It also gives one hope, as the historical record also indicates that cultural human capital is also transferable. The transformation of the Irish diaspora from their utter destitution to their descendant's current place in 21st century society should tell you that. (Some historians would place the average displaced Irish peasant's wealth at something like 1/2 to 1/4th that of the contemporaneous average US slave's.) Such a reading of history also demolishes the ideology of the worst segments of the Alt-Right. (As well as demolishing that of the identity politics US far-left.)
Let's call such a world view, "Cultural Primacy." Given that cultural human capital has such deep-rooted and powerful effects, what conclusions could we draw about Google's policies? It could well be that cultural human capital would have strong and persistent effects on the preferences of groups, so it would be unreasonable to expect immediate 50/50 outcomes. In fact, it would be expected for such changes to be generational, perhaps taking 2 or 3 generations. Such a world view would also emphasize the educational pipeline, and the way the subcultures of professions and fields are perceived by under-represented groups. This also happens to be in line with James Damore's suggestions from the memo. It's also entirely in line with what Google and YouTube execs have said in public:
