I think it can be a matter of self defense and an oppositional behavior just to make sure one is not led by someone else. That is fixable.

What I have worse issues with is people who sugarcoat and hide their judgmental attitudes, I have been unfortunate to met those before I came here. Some people are pros at saying mean things with kind words. Those people don't want a healthy approach.

One who is reactive and defends self is not a lost cause in the same way, they can change their reaction pattern because they don't really want to hurt people, they just want to defend themselves and they can find other ways.
