"becoming an adult" is a thing people do, this will include no longer agreeing with everything your parents taught you. This is mundane and what you have described.

"my parents are/were abusive" is something a plurality of people (and especially those raised in evangelical churches) experience.

Within that dynamic, the 'value' at issue here is 'Do I, your child, have a right to my own body and choices?'; Too often, the reply to that is 'no, we expect obedience and obeisance to God, your father, and your mother, in that exact order, because that is the one true way'.

This is a form of domination, not well-meaning 'protection'. It does, in fact, 'mess people up', in their intimate relationships most of all.
