By that logic if your parents fed you cocaine for breakfast it would be alright for you to do the same to your kid.
One of the things parents should strive for is to improve themselves and their parenting skills, not just roll over and mindlessly repeat past behaviors that are known to be harmful.
I think you're saying I'm saying more than I'm saying. The logical statement isn't, "my parents did it to me, therefore there's nothing wrong with it."
It's more like, "Using a switch was very common place in our society back in the days of my youth; it did not harm kids and generally produced responsible kids when done with appropriate diligence and care, therefore there's nothing wrong with using a switch as punishment." The fact that society has become meddling pussies is the focus of the lament, not that parents should be able to do to their kids whatever their whim.
My OP was made before the later information came out. The initial reports I heard and the photos that were posted made it seem to me a whole lot like it's AP's business and none of anyone else's. But as more information came out, including AP's own words, it became obvious that what he did crossed the line completely. I think the charges against him are absolutely appropriate.
