“Is it discrimination? Well, of course it is. But that cannot be the end of the discussion. We are so robotic in America whenever the word ‘discrimination’ is used that we shut down thought and all genuflect in the direction of whoever is complaining. But the proper question is not whether it is discrimination but whether it is justified.

Of course passengers would not be nervous in the presence of six priests or six rabbis. Neither of these groups has any history of blowing up innocent people. Nor do Americans despise those who pray. In fact, uniquely among Western democracies, we are great fans of religion.”
