It's quite illuminating that both you and your parent are making unsubstantiated claims (I'm not criticizing, just observing), but only your comment gets downvoted. I believe the reason is that you are expressing a forbidden idea, a taboo. "Behavioral differences based on sex? What next, are you going to compare races and then grow a narrow mustache?" People are so afraid to find that not all humans are equal in every respect other than body that they are willing to stop, mute, censor any and all discussion on the subject and even block research into human nature rather than face the danger of having to deal with this (granted, difficult) issue.
