Once you think it's all right -- even holy! -- to hit your own beloved children, your own flesh and blood, what do you do to other people's children? If you're willing to beat your own children with plumbing line, what do you do to the children of your "enemy"? You torture them. You rape them. Because if the children you are supposed to love deserve beatings, the children of your enemies must deserve so much worse.
Stop it. Now. No excuses.
