Arrogance or Ignorance?

One thing I absolutely hate in a person. Arrogance. I can't stand people who are arrogant. Why does a person think that they are better than anyone else? Especially if that person thinks that their money, wealth, fame, power or the way they look gives them the right to think that they are above others. In a way I understand those type of people and its so easy to be arrogant about what you have forgetting that one day they will die and they will be worthless.
What I don't understand are people who like me, are normal, living a normal life, having little or no influence on the lives of other people, who happen to think that just because they were born in a land where you receive a document that states you are a citizen of the USA or Canada or Britain, then that makes them the ultimate humans and that people from different parts of the world who happen to be born in countries that are not so wealthy, and have little opportunities, are less human or "sub-human" or "inferior humans", who have no values and no sanctity for life.

Ironically at the same time when they are classifying people from different races, they also claim that the nation they belong to is fighting for justice, and or fighting to save humanity.

I don't know of those people are arrogant or just ignorant, or is it because of their ignorance that they are arrogant?..

anyways, in chapter 14 verse 13 of the Quran, it says:
Oh mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that you may know each other (not that you may despise each other). Verily the most honored of you in the Sight of Allah is (he who is) the most righteous of you. In addition, Allah has full Knowledge and is well acquainted (with all things)”.

A Hadith of the prophet peace be upon him where he says,"Oh Mankind! Your Lord is One. Your (grand) father is one. All of you belong to Adam (peace be upon him). Adam is created of soil (earth dirt). Truly, the most honorable person in the Sight of Your Lord, the Almighty Allah, is the most pious among you. There is no superiority for an Arab over a non-Arab. There is no superiority for a non-Arab over an Arab. There is no superiority for a red (race) person over a white person. Likewise, there is no superiority of a white over a red (race) person except for the level of piety (mindfulness of God, the Almighty Allah in life and practices)" [Ahmad, Hadith No.411]
