I have a mixed opinion of all this and I'll explain. I don't believe in violence, except in self defense. There's also times where a person is so unbearably rude that you secretly wish you could just punch then in the nose. A person can try to make sense to one of those idiotic people but it just doesn't penetrate their thick brain and that's when a swift punch does the trick. I'm all for defending oneself when there's no other option.

My daughters now a black belt and she could literally do severe damage but she uses self control. She has occasions when she had to twist the occasional arm and once flipped anther boy - she warns them first and if they touch her first she uses the karate to basically get them off her, then they realize the mistake and run off. She won't continue with force unless they continue.

It sounds like Mandy has a rage problem, most likely from her abused relationship. Sometimes the victim can become an abuser - they get so sick of being the victim and the rage builds up...they swear they'll never be at a disadvantage again. I think she should get into therapy to control this anger. She should only use violence as a last resort and only to defend herself. If she doesn't get control of this, she could get hurt one day or they might take revenge at a later date when she's not ready.

Another thing which concerns me is, what if one day your relationship goes sour and she turns on you? What if you end up having kids and she gets so mad she ends up abusing your kids. This anger and rage has to be controlled.
