Christianity breeds arrogance, a chosen-people mentality. It's only natural that those who believe (or play act at believing) that they have a direct line to the Almighty would feel superior to others. This is so obvious that it needs little elaboration. A brief look at religious terminology confirms it. Christians have often called themselves "God's people," "the chosen people," "the elect," "the righteous," etc., while nonbelievers have been labeled "heathens," "infidels," and "atheistic Communists" (as if atheism and Communism are intimately connected). This sets up a two-tiered division of humanity, in which "God's people" feel superior to those who are not "God's people."

That many competing religions with contradictory beliefs make the same claim seems not to matter at all to the members of the various sects that claim to be the only carriers of "the true faith." The carnage that results when two competing sects of "God's people" collide—as in Ireland and Palestine—would be quite amusing but for the suffering it causes.
