I personally DO. First of all there is a BIG difference between spanking your kids and abuse. It's how I was raised and it's how my kids will be raised. Now jerking a child around, hitting them because you feel like it, leaving bruises, knocking them around, knocking them down, slapping in the face, pushing them into things, etc. To me that's abuse. A pop on the butt or hand and being told no when they are doing something they aren't suppose to do is discipline. I'm sorry but time outs and grounding only go so far. My 2 year old is better mannered and and more well behaved than my friends 4 and 7 year holds who have no discipline and just get yelled at, and her philosophy is well I'm not going to whip my kids for something they don't understand.... UUUMMMM that's exactly why there are 13 year olds telling their parents fuck you I don't have to listen to you, and 15 year olds getting pregnant at such a high rate. It's sad really. But I am a perfectly functional human being and I was spanked as a child. I don't understand why kids can get away with EVERYTHING today.
*EDIT* Probably should've put this in before but my 2 year old knows his boundaries and when me or my husband get that 'tone' he knows when he's gotten as far as he can go. We try to tell him at least twice before we spank him, but if he keeps doing the same thing again and again we will. But no I don't see a point in that being the only discipline a child gets but in some cases it is eventually needed.
