When you put someone down, it says more about you than them, right? That's what you're recognizing and are unhappy with yourself about. So, the flipside to that, is when someone puts you down, why is it again about you and not them? Or, when you attack someone else, you beat yourself up for it. When someone attacks you, you take it to heart (and retaliate) rather than putting it back on them like you should.
Own what is yours, and let them own what is theirs. Be slow to take offense by recognizing a jackwagon when you see one.
