> I'm surprised to see this ranking so high on HN. Sex-based difference is the biggest taboo of our time.

Indeed, it's such a taboo that it's brought up here every time the subject is discussed here.

Unless you would take all your information from radicalfeminist.com, I never saw a reputable news channel denying there would be differences between sexes. Actually, I see this meme of "Gender differences are taboo!" MUCH more often than I see the actual behavior so decried in actual action.
