Ask any British, French, German, American, or even Saudi person, whom do you think is the best 'people' in the world, and they will tell you without a blink of an eye that it is their nation which is the best (even without a citation from the Bible or Makhzor). So, there's nothing wrong with us thinking we're the best, chosen, etc. Moreover, we were definitely "chosen" in the past to be the target for pogroms, destruction, exile/deportation, annihilation, inquisition, forced conversion, blood-libels, holocaust, and what not.
