Dh's mother used switches and fly swats on her 6 boys. Once she even used a piece of a garden hose and many times used a belt. NONE of them felt abused nor do any of them abuse their children. They couldn't have a closer, more loving family. Could she have handled it better? Maybe. But she had 7 kids, worked full time running a store and owned a farm--she didn't have time for time outs and such. And it worked.
When a child is punished by spanking its silly to say "did you mean to cause pain". Well, yeah. Why else would you spank? What other purpose does it serve?
My own kids were swatted when they were 4--would never have used a switch on a 4 year old-- and I am sure spanked a few times when they were older, especially the two boys. Switches and belts and such were not used by our choice; but I did use a ruler type thing a few times when they were much older than 4. But was that swat supposed to hurt at least for a moment? Yes, it was.
I don't have an issue with a child being spanked at all. I know that sometimes it is the best way to get through to a kid. And some of you can tell me different from now on and it won't change my mind. I have seen it first hand.
I do have an issue with the marks that were left on this child. I do think maybe this player needs some parenting classes and anger management if its deemed necessary. You have to understand that spanking a child like that may not come from anger but from thinking its the only way to punish this child which means he needs to learn how to parent in other ways (along with spanking if he feels that spanking is ok) I don't think he needs to be banned from the NFL or even necessarily suspended.
Edited to Add: Please stop putting all the players under one label. I am so tired of hearing "the NFL players are sooo violent". They don't all switch their kids or hit their wives or fight dogs. For many its more of a product of where and how they grew up than it is playing football. All players do not do these things.
