I understand where the attitude of not backing down is coming from; I mean I used to be exactly that way with raging hormones and emotions. In a way I sort of blame it on not focusing on some internal arts and slowing it, because back then I was heavily based in Muay Thai and trained for the sole purpose to win and mess people up. I had nothing to slow me down and remind myself about the main reason for martial arts. The main goal of any good martial art system is basically for self-defense, whether you use passive aggression or lethal force is based on the individual style.
When you let yourself just flow naturally in a fight sometimes you cant control what happens and go "crazy". I have done that and probably done some f**ked up things to people when I let loose, probably under the influence or something in that sense. Responding to Hearwa, I say its perfectly naturally and part of the learning phase of trial and error. Every practioner experiences this type of situation sometime in their life. Learn to control and manipulate the other person to your liking is what separates the students from the masters. My old kung fu teacher used to tell me that students would usually fight, leaving their opponents far away from them, but a master can force a person down in front of his feet. That type of control is hard to learn, but that's also part of the joy in Kung Fu.
As for a permanent attitude change, I basically let people talk as much lip as they want to towards me, having read in some Buddhist scripture," A person can only yell, degrade, and torment you for seven full days before they have nothing left to say." It helps me keep patience and humility in mind, but I will easily try to defend others around me, like my friends and family. Defending a girlfriend/ future soulmate is within bounds, as people have no right to talk like that to the people you care about. I let others talk as much as they want, because I have the confidence to back up my skills if I need to.

Many famous fighters have done this (roy jones jr, chuck norris, Morbicid, etc)"
