Muslim superiority

What do you think of born Muslims looking down on non Muslims or non-believers ? The way I see it is that we are not better than them because we are more religious or conservative as we turned out religious because our society was like that therefore I don't understand why many Muslims look down on Muslims as we were born in Islam we didn't choose it ourselves so it is like a geographical coincidence or a mercy from god not something to brag about or think we are superior than non Muslims and also calling them kafir as an insult, what do you think ?
