I never mentioned any of the theories in your response. There are all kinds of people who study gender in society from every possible angle, Damore doesn’t strike me as an expert in the field. Just a typical engineer who thinks he knows everything.
Moreover, a person's field of expertise doesn't have any bearing on whether their ideas are correct. It may go to explain why their views are the way they are, but it doesn't necessarily follow that a person is wrong about something scientific because they aren't a scientist, for instance.
Nor does their expertise preclude them from succumbing to personal or institutional biases.
FWIW, Damore has a masters in systems biology. This fact was fairly widely reported. So, you can fall back on the facts instead of your own biases (what "strikes" you).
