I dunno, everyones going on about if the roles were reversed, people would have stepped in. There s a video out there where a bunch of actors basically recreated this scene to record peoples reactions. Most people walked by but eventually the "abusive girlfriend" was brought down by women. My theory: the same reason why the man in this video didnt fight back is the same reason no guys made any effort to stop the girl, when a man see s a woman being hit, its his job as a MAN to intervene, because it takes a male to stop a male. Is it still all about gender roles? Yes, but not in the blatant, "people think its ok for a woman to beat a man" kind of way. The majority of men are taught to be protective of women, even if they re not conscious of it, so when they see a woman beating a man there is no urge to stop it. And i think women in general are loathe to become involved in a physical altercation that doesnt involve them.
