Congress shall make no law respecting an establishment of religion
Just throwing this out there....If the government allows a statue to be placed on government land for Christianity, how can they not allow a statue to be placed for another religion?
And to preempt the "The 10 Commandments are for Christians and we're Christians and we've always been Christians" argument....
The 10 Commandments were part of the Jewish law, not the Christian law. Unless you're keeping the Sabbath holy, the big ten AREN'T your religion.
