Before I get to the topic at hand, the 'message board' link on L&E is broken, since, as you might recall, they've moved the boards.
Now, about the article... I honestly can't percieve how you think spanking kids is going to do any good.
Now, I myself have a younger brother. There are those times when he won't listen to reason, and there is a great desire to spank him (if not more). But there are two big problems with such a path of thought: First, if we teach our children right and wrong through violence at an age when they can already see reason, it will be rooted in them that violence is an appropriate way to deal with problems. If you try to say that hitting people is wrong, they won't take you seriously, because you've hit them yourself.
Second, on rare occasions, we did spank my brother. It helped for exactly crap. Do you think that at a point where a child is too stubborn to listen to reason, he's going to be swayed by violence? He'd cry, be he wouldn't stop doing whatever it was that he was doing which was wrong.
You could say we weren't hitting him hard enough, but I think that causing physical damage as a method of education is a bad enough idea for me to not have to explain.
I apologize for the serious tone of this post, but I really do want to know why you think spanking's going to help anything.
