I really hope this douchebag is joking, though I don't think beating your girl is something to joke about.
It takes a really, really weak man to beat a woman. The only men who beat women are pussies who are so insecure and so little respected that they have to make a woman physically afraid of him for her to listen. Bullsht.
It takes more strength to restrain yourself than it does to beat a person. Beating women is for cowards.
