I think much of this discussion at hand is how we perceive ourselves and the world around us. From experience - hence my opinion on this - I know that life gets so much better when you admit to yourself that you are not perfect, that you cannot solve every problem in the world, that you are not always right, and that you have much to learn. Maybe its just being humble.
I know I may not always follow every rule in the world, and that I am nowhere near perfect. Yet I set high standards in life, and I try to live by them. Does this mean I think I am better than everyone else? No. I'm human, just like everyone else. I understand that, and I make every attempt I can to try to act in a better or more responsible manner.
If everyone stopped trying to act like they alone are right, and started to accept that both sides to every argument may have valid points, then the world would only become a better place. Remember that old saying, that you should always listen twice as much as you speak? It can and still does apply today, with the exception that maybe listen can be replaced with "read" (or "think") and speak with "post".
