One reason, perhaps, is that too many "differences between genders" discussions (whether it's from one side or the other) devolve into unhelpful discussions about confirmation-bias style "superiority" or "discrimination" and the like. Discussions that try to honestly determine more fact-based reasons for the differences (whether it be biological reasons or social constructs) are rather rare. In this case, that observation was part of a "I have strong hacking skills" boast. So more "oof" for the awful overall tone. I personally suspect a bit of Dunning–Kruger here. My hunch is, while it is true that women in infosec are rare, there probably are women in infosec that have quite a bit stronger skillset than this guy.
