My biggest problem with all this is how the author gave absolutely no thought to how his female coworkers would be affected by this. These are REAL women who have to interact with him every day. They are not just statistics who are on average less likely to be good engineers than he is. They are supposed to be on the same team. I can't see how any of his women coworkers wouldn't think of him differently after this.
This was not a paper released on the internet with no ties to his coworkers. By sharing it at work and tying it in with google he made it personal. The women reading it have no choice but to make it about them, because it is about them! They are the ones who interacted with programs that he is against. Everything he talks about is stuff they actually experience. And throughout the entire thing he shows that he does not care at all about these women.
