That’s some dumbass sexist bullshit which was/is wrong on so many levels. First, it degrades women by equating them all with “delicate flowers” who are supposedly incapable of doing any damage. Second, it implies that domestic violence is acceptable, or at least not as serious, if a woman is the abuser and that a man, supposing the victim is a man, should not be allowed to defend himself. For normal people, not to mention someone who sells himself as a sort of therapist, that’s some fucked up logic.
As a general rule, nobody should be hitting anyone else. Gender is irrelevant. If someone is assaulting you, and you are unable to get away, then you should absolutely fight back until your attacker stops attacking you. Once again, gender is irrelevant. The fact that “Dr.” Phil’s tiny little brain can’t comprehend that is simply mind boggling.
