I agree with you while spanking is okay using a belt is too much with your hand you can tell to an extent how much pain you are inflicting with a belt that is extreme and you can't possibly tell how hard you are doing it.

I think spanking should be used if it will teach thee child in the long run but each child responds differently to different punishments while one child just telling them no or grounding them will work on another child it may take a spanking to teach them right and wrong.
