Well there is that, the bad parents have made it bad for rest.
But I remember kids coming to school when I was a kid all whipped up welted up by their mothers, with a wire hanger and other stuff, telling stories about being dragged down the stairs by the hair, it was truly horrifying. My upbringing was bad, being routinely knocked down by a parent, parents using shoes, melamine plates, metal spatulas, being pushed, thrown, etc. I actually thought it was normal, that everybody lived like that until I saw other families didn’t act that way. So I am super sensitive to immature, selfish parents that don’t treat their kids right.
The bad parents haven’t made it bad for the rest, the reaction to the bad parents has made it bad for the rest. There is no excuse for beating (not spanking) a child. But neither is there an excuse for the behavior of the government in many of these cases; beginning with the assumption that the parents are bad.
I was whipped as a child. There were times I had welts. But at no time did I ever doubt my parents’ love. The only physical punishment was a spanking, never the things you describe...and I was a problem child. I was never knocked down or dragged or struck with the handiest tool or a fist - always measured, always the same strap, always told why I was getting the spanking(usually forewarned).
I understand your sensitivity, but it is wrong to try to punish your parents through other parents.
