I was reminded by seeing this question regarding racism that I had always wondered about how to interpret the well-known prayer of "Aleinu". The first half of the prayer seems to be thanking Hashem for making us uniquely believers in Him, in other words, we are happy that we are the only ones who serve him. This seems like a step further than merely thanking Hashem for singling us out to give us the Torah or the like, because we seem to be happy about the fact that other nations continue to worship idols.
Not only does such an interpretation fly in the face of most people's intuition that we really do want the other nations to also believe in Hashem, but it contradicts the next paragraph of the very same prayer: we hope for the day when all nations will bow to Hashem.
Are we happy about the fact that other nations worship (or worshiped) idols, which is what give us our uniqueness?
