> what causes first, the asocial stigma? And what causes our society to keep girls from asocial activities?

In most western societies there is very little that keeps girls from these activities. But then there is the boob tube, watch some disney channel and study the stereotypes present in the shows. It kind of answers both questions. But it is not only Disney Channel I would consider it pervasive in western culture as a whole. e.g. Like TV shows like The Big Bang Theory.
