This topic annoys the crap out of me!
There are dopes on both sides. One side tries to change the argument by lumping a spanking in with a close fisted punch to the gut. The other side will try the label child abuse as "corporal punishment." They are both equally idiotic and as in all such arguments they detract from the real issue.
A good parents needs to know when natural consequences are sufficient or when there should be additional correction. Do you let the kid touch the hot burner and learn the "hard way" or, do you smack the hand or, do you try and reason with them? Having been in this situations (4 kids) I'm not letting my kids risk injury like that. My boy once was hell bent on touching the grill. First time i simply said no, but when he stared me down, little hand inching closer to the grill as I said no again, I knew he needed to understand what he was doing was wrong. My options? Let him fry his little hand on the side of a 500 degree grill or demonstrate with a calm but swift swat to the butt? I'm sure you can guess what I chose. You tell me, what is worse?
Like I mentioned earlier, I, in no way shape, or form condone child abuse but, don't tell me that, when properly applied, a spanking isn't an effective and humane for of correction given many of the alternatives.
flame on!
