Women can enjoy reading, learning, and thinking about men and masculinity. Men certainly do so about women and women's issues (even on Hacker News). If we take the logic in your post to its natural conclusion then any articles about women's issues (e.g. sexism against women in technology) shouldn't appear on the site, which is patently absurd.
I actually agree that this article shouldn't be on the site, but only because the theme has absolutely nothing to do with programming, startups, entrepreneurship, or business which is Hacker News' bread and butter. Not for the reasons you do (which are silly).
