Children should never be hit. You wouldn't hit your teeenager if they did something wrong. If you did, it'd be considered domestic violence. And that, as we all know, is a bad thing. You're hitting them for a practical reason, for your own benefit usually, as it makes them shut up. This is along the same lines as the stuff we do to animals in battery farms. Well, in the loosest sense, but a connection is still there, I just can't put it in words.
