Do you think men and women training together normalizes violence to women?

So I was talking with a friend (he never trained BJJ but did boxing for years) about training at open mat. I was rolling with a guy and while trying to pass I got a knee to the nose, pretty sure it broke, lots of blood. My friend then replied with, "this is why I don't think you should be training with men" I said women roll hard too and an accident like this could've happened with either guy or girl. Then he went into a whole argument about how men and women should never train combat sports together because it normalizes violence to women. That a guy who never thought about hurting a woman would train with one then find he enjoys it. Then goes out into the world looking for more victims. I was just like wtf are talking about. To me that sounds like the craziest logic. That kind of psycho sadistic shit isn't learned in a training room. He brought up never live sparring with women when he was boxing, which I get. But training BJJ is different. He told me it was morally irresponsible to train with guys but I think if he'd ever experienced an open mat he'd change his mind, thoughts?
