The entire psych industry followed the same path. They think signs of equals full raging case. Beforehand, it had to be proven to be a problem first for a diagnosis to be needed. Far worse, they're all trained to recognize problems and not good life, so a parent putting reasonable restrictions might be considered abusive because that's all there is to check for.

The feeling of helping is way stronger than recognizing reality, and it's caused some horrific parts of history.

The reason why it's so hard is because raging abusive parents know how to hide the marks or scare the kids from talking. I have a foster kid that regularly comes into my home, has obvious signs of abuse and mental problems, and is then given back to the parents because they lied well enough. I can't publicly talk about it because it's against the law to even publicly say this kid exists in my life. There is enough evidence to remove the child but not enough to keep it that way.

Teachers are told about these parents, so all they see is that. It's a vicious cycle of evil.
