I was brought up with the odd smack on the top of my leg. Not many maybe two or three I was a fairly good kid. I do not class it as abuse my parents where/are loving caring parents so I don't think you can make a blanket statement about all smacks being abusive. I was upset with getting a smack but not resentful or angry.

I really do feel its how it is dealt with, if in anger then yes it is wrong.
