Should cities be able to pick from among religious displays?

The U.S. Supreme Court is considering a case today on whether Pleasant Grove City, Utah, violated free speech rights and the Establishment Clause of the Constitution. The city allowed a national group to place a Ten Commandments display in a city park but then denied another religious group from placing its own historical display. The 10th U.S. Circuit Court of Appeals in Denver ruled that the city was free to ban all displays if it wanted to, but that once it decided to allow the Ten Commandments it had no right to bar the other display. Do you agree?
