You use the word "therefore", but it is in the connecting logic between your first and second sentences that Damore brings in a lot more than biological differences. For example, he claims that the opinions of staff at Google are clouded by leftist ideology, and that this determines the manner in which it attempts to increase workplace diversity.
Again, I am neither advocating for or against the truth of this. I'm pointing out that Damore did more than simply highlight biological differences. I think that's important because the shallow way it is discussed - e.g. in the linked article - only leads to divisiveness.
So, you think that his statements garnered controversy because he proposed policy amendments and didn't simply leave things at "innate biological differences might explain these disparities better than bias"? I think that's a pretty profound misreading of the situation.
