Your parents are psychotic, and if I were you I would get the fuck away from them ASAP, if not I'd beat them with my bare hands.

What they did was crazy over the top, and you don't need to deal with that shit. I'm sorry to hear there are parents like that still around, it sickens me to death.

There's no point in reasoning with people like that, just pack up and leave, and tell them "see you in hell, assholes" cause that's all they deserve for the shit they did and said to you.
