Uh, no. It's an example of a private property owner deciding what sort of decorations to put on its property.
The courts have decided, assissted by their co-cospirator the ACLU, that schools and other governemnt owned buildings, institutions and even city parts (for cryin out loud) can have no religious displays or expressions. The ban on religious freedom is seeping into the rest of the public. Everyone is afraid of effending the one snotty atheist who will hook up with the ACLU and do a lawsuit.
Religion is becoming "dirty", something to be ashamed of, - hey, it's supposed to be in the closet, and murals glorifying sodomy are given the state imprimature (sp?). As in the city or state owned community building in Philadelphia which is proudly emblazoneed with a mural depicting the glorious history of sodomy. That's allowed. Boy Scouts in a publicly owned park? No way - as recently decided in San Diego. The reason stated? Because they "discriminate" against sodomites, they are a RELIGIOUS group and can't use the park.
