And in what reality do you live, I do agree that there a few women out there wh do know how to stand up for her self, and usually that end up with a prick who thinks having control over someone half his strength and size, makes him a man. The majority enjoy letting there man believe that he is in charge, which gives who the power.
Any asshole who thinks this will make her a better person is deeply disturbed, and believe me if she bit him hard enough, he would never stick it in her throat again. This type of action is usually only good when it is something she wants, not what she it made to do to satisfy and individual that has no ideal how to love to treat another human
