Sounds like a good boot camp to me.The parents consent to this when they enroll their student there.And they sign a declaration that they will abide bythe schools code of coonduct rules and regulations, read beforehand.
And this is abuse? I can think of a lot of teens who would benefit from boot camp.
Consent into being kicked? How were you able to learn this?
I suggest you withhold food and water from yourself and go out and run a mile in your bathrobe.
