Well your self-justification and rationalizing in the face of obvious behavior problems for a start. Then your retreat to the old "you're not in my shoes" canard.
But tell me, how could someone "politely" approach you to complain that your child was a little hellion? This is not a challenge, but a very real question. I know parents whose toddlers have attacked the family pet with a weapon that display that same bifurcated sense of civility you have displayed.
Also, please explain the reasoning behind "you are allowed to have your emotions?"
