That's true. But all the steps taken to keep parents from crossing those lines have failed.
We tell parents not to hit their kids. That's the subject of an article in Huffington Post, which essentially tells parents "Don't hit your kid. Ever." A lot of parents reading that are at the end of their ropes, and they'd probably respond by saying "Don't tell me not to hit my kid! You don't know my kid! You haven't had to put up with my kid for the last (insert number here) years! I HAVE!!", especially if they believe their kids are dramatically different from most kids. Kids are not carbon copies of each other like the cars rolling off an assembly line.

We also say that if you suspect child abuse,.you should report it. With the exception of teachers who are legally required to report suspected child abuse, most of us have too much going on in our own lives to pay much attention to kids who aren't ours. And if a kid is so bad that everyone in town hates him or her, I don't think anyone will complain if they know that child is being abused by their parents. They'd just think that kid was getting exactly what he or she deserved. They'd probably cheer and celebrate if that kid died.like everyone cheered snd celebrated when Navy Seal Team.Six blew Osama Bin Laden's brains out.
So instead of telling parents not to hit their kids, I'm telling kids to behave themselves and not make their parents mad enough to hit them. I'm telling kids that if their parents hit them, most other people would probably hit them too.
