How much child-beating do you believe is sensible?

Are you saying they should never be stoned to death in the public square? The bible says otherwise.

If a man has a stubborn and rebellious son who will not obey the voice of his father or the voice of his mother, and, though they discipline him, will not listen to them, then his father and his mother shall take hold of him and bring him out to the elders of his city at the gate of the place where he lives, and they shall say to the elders of his city, ‘This our son is stubborn and rebellious; he will not obey our voice; he is a glutton and a drunkard.’ Then all the men of the city shall stone him to death with stones. So you shall purge the evil from your midst, and all Israel shall hear, and fear.

Are you saying children shouldn't be hit with a rod? The bible says otherwise.

Whoever spares the rod hates his son, but he who loves him is diligent to discipline him.

Folly is bound up in the heart of a child, but the rod of discipline drives it far from him.

And before you say something like "it's actually a shepherd's rod used to guide-" Nope, it's explicitly for striking children:

Do not withhold discipline from a child; if you strike him with a rod, he will not die. If you strike him with the rod, you will save his soul from Sheol.

I called my mom a bitch because she made excuses for abusing us instead of admitting it was wrong. Should I be put to death?

For anyone who curses his father or his mother shall surely be put to death; he has cursed his father or his mother; his blood is upon him.

People like you are the reason my parents are getting away with child abuse.
