As a matter of fact there was a big stink a few years ago about a religious symbol, I think it was a crucifix which was in a jar of urine. This was supposed to be "art." The debate was over whether the government should be funding that sort of "art," and not whether that "art" should be banned.

Freedom is about allowing this sort of thing to go on no mattter how much it offends people. I am a liberal, I am somewhat religious, and I find a cross in a jar of urine to be about as artless as it gets. But I would fight for the right of the individual who made the thing to be free to do so.
