Joe Biden says he can think of nothing inappropriate he has done. And that is exactly the problem. Joe, ask yourself, "Why don't I sniff men's hair and kiss the top of their head?" Beyond the fact that a man might punch Biden in the face if he did, is the perceived power that such men think they have over women (and not other men). Adults ruffle other people's children's hair for the same perceived power difference. A sense of unconscious entitlement.
