Women don't need to know how to defend themselves from other women, they need to know how to defend themselves from men.
I agree with that and I mentioned this in my post up a couple from you.
Another point that hasn't been mentioned is (if he is taking it for a self defense related reason) what would he do if he happened to be attacked by a woman? It does happen. Would he just accept the violence because he isn't allowed to touch her? Or does this cross a line that allows him to protect himself?
Sorry for my ignorance here, but I really don't know how strict this is to be followed. There are so many religions and so many different levels of each of these religions. I feel so ignorant outside of what I do.
