What would you do if your parents hit you?

That's not the answer, they'll only hit you back much, much harder.

I guess they're going to the nursing home when they get old.

I agree. Everyone has a breaking point, and we should avoid pushing people to theirs if possible.

That doesn't guarantee CPS will swoop in and save you. They might not believe you, especially if you don't have marks or bruises. And if they do place you in a foster home, the foster parents might treat you just as badly if not worse if you say and do the same things that led to your original parents hitting you.
