I see you have that Classic Liberal mentality of "Do not protect me from my own stupidity, give me all the relevant information and let me make my informed decisions as a responsible adult"

I do share those sentiments but they don't fully describe my position I'm not focused on the mental stuff.

Even in possession of all relevant information, you may find yourself making the wrong decisions because you're not quite in your right mind. I don't know about you, but when I am high on sexual arousal I can barely even talk.

I might make decisions that bring me emotional pain, but then I'll learn worthwhile lessons.

it is possible that the other person is unwilling to share all the relevant info with you (privacy, information hazard, shame, cowardice, dishonesty) or even unable (they don't know or they can't properly put it into words)

I think it's very useful to learn nonviolent communication to express your emotional needs to give the other person the information he needs.

I however wouldn't say that everyone has to learn nonviolent communication because it's not the only model that works.
