Its a good thing but yet a bad thing..
For that good points for spanking.If a kid dose some thing wrong and gets spanked he/she wont do it again or thing twice before doing some thing wrong.Its happened to me ones or twice before but the one time i remember the best was when my grandmother spanked me.
I made the mistake of saying f*** you to her when i was like 5 i think.Oh boy that was one bad mistake on my part she spanked me so hard ,couldn't sit down for a while lol. But i learned my lesson extremely fast do not say that to an adult and especially to her,for i did not want that again.Allot of people that get spanked turn out all right and are not "scarred for life" which some politicians want most to believe.
As for that bad points to it, Some people take it way to far with spanking.To the point it would be called child abuse.Which "some" may think is ok to do if a kids dose wrong.In those cases the parents should be locked up promptly and with out question.
