Let's say pick them up and throw the child. Seems legal, saddly. However, it would probably anger you to no end as a parent since they hurt your baby. Any good parent would be ready to take the neighbor by the throat. Hitting the child seems just as bad as throwing them.
Children are our future.
I'm pretty sure that went out of style around the same time our country was founded. Or we could make a really big leap and reward good behavior and crazy stuff like that. NOT hitting children isn't going to spril our civalization down into darkness. It's hitting them that gave us disiplin problems in the first place.
