Your response makes a lot of sense. It is a shame that after people like Summers (or that Google guy) talk about these issues, the talks about how to attack whoever wrote the piece drowns out attacks on the idea. It may vary well be that your theory is right. In that case I would hope that the discourse would go as follows. Summers submits an article about how variance is the reasons for difference between men and women in careers. Then someone like you submits an article explaining why the first theory is incorrect. Then Summers explains why your critic is incorrect. After enough back and forth, other scientists in the field start to join the conversation, some agreeing with Summers other with you. After enough time the scientific consensus gravitates to one side.

However currently whenever someone talks about this, the response is not "let's argue your conclusion" but rather "burn the witch".
