Okay? Separation of Church and State mean anything to you? I would be no more in favor of Islamic or Jewish displays on public property (not that I really care). And I'm sure Christians would scream Bloody Hell if there were Islamic observances on public property.

Okay? Never bothered me. But, I guarantee that Christians would once again be screaming Bloody Hell if it was a place of worship for those that believed in other religions.
Heck, Muslims have issues getting building permits to build their places of worship here in the US.
Christians look laughably stupid when they try to play the persecution card. They've done (and continue to do) their fair share of persecution.
