In fact, I think the Constitution demands that.
Yeah...there's one in Ohio where some teenager and the ACLU are suing for the right to put up a giant statue of a penis because the kid says he's started his own penis worshipping religion. Even though he's the only member of it, he says it's his right to erect his statue alongside the Ten Commandments.
This stuff is why I opt for the historical/cultural argument whenever possible.
