The intersection between the set of sociopaths and the set of university professors is not necessarily empty. However, claiming that this behavior is normal among males is outright sexist defamation. It's like, after sharing a story of being robbed by a black person you said: "You might think my robber was an antisocial person, but no -- they are a normal black person"

I also felt while reading this that my sex as a group was being defamed, but while I doubt that the author has the evidence to conclude that such behavior is truly typical of males in general, I also have to be skeptical that my own experiences are sufficient evidence to suppose that such behavior is atypical. Our own social circles tend to be very heavily filtered compared to the overall population, and just because the behavior the author wrote about describes few of the guys I've associated with, doesn't mean it's not normal.
