How about if they post the Code of Hammurabi instead?

My personal impression of some people is that they don't want to be exposed to anything religious because they're afraid they might be tempted to join that religion, whatever it is. If it brings something good into your life - what's the big deal? Do as you please and let others enjoy the right to do the same.

Religious zealots may make a lot of noise now and then, but in the US they're a microcosm of society. It doesn't do to pay them much mind.
