I agree with every point you made. Personally I've always found saying no to be as easy as saying yes. Guess I'm just wired differently. (I happen to be bit of a posterboy for ENTP-Assertive personality type)
I must also add the "Yes" that is told as a "No". Basically it's turn the other cheek done right. Think about scene in Fight Club where the owner of the place they have their Fight Club beat up Tyler Durden. When someone punch you expecting resistance, saying: yeah, go ahead is bit of a F**K You IMO.
I didnt quite follow you until you mentioned the fight club analogy. Yeah theres something about that type of yes no that feels good depending on the circumstance. I feel you there!
