"The very act of calling America a "Christian Nation," for example, is at a
bare minimum a symbolic attempt to describe America in Christian rather than
secular terms. A "Christian" nation is one in which the Christian beliefs of
people or institutions become relevant to their status in the political
community. We would not all be equally "citizens," but first and foremost
"Christian" as defined by the state or "not Christian" - and thus politically
inferior.
This, then, means that the assaults on the separation of church and state
are, in the end, also assaults on not only liberty and freedom, but also on the
very concept of citizenship in a liberal democracy."
