Exactly I would expect dads warn their sons of crazy women also.I raised two sons who are gentlemen. One father showed my elder son his shotgun and my boy offered to help him clean it. My son was in more danger from the daughter than she was from him. That relationship didn't last long. Thank God.
Boys should be raised to respect women; they learn by example of what they see at home. End of sermon.
BTW, they are both married to women who are very different from each other, but each is beautiful and wonderful in her own way.
