Some leaders think they have the right to abuse you.

I think it's okay to submit to a teacher. I have, and a few times it's worked out to my benefit.
But there are dangers. Some teachers think that submitting to their teaching means submitting to anything they require. None of them would admit it's abuse. They would never do that. But they do¬†think that since you're their disciple you should think and do anything and everything they ask. They equate voluntary submission to complete docility.
They feel that since they feed you they should be able to eat you.
