"The Fraternal Order of Eagles did not erect a momument; they gave a monument to the city, which then decided to place it in a public park. The Summum church has a similar right to give a momument to the city, but the city gets to decide what they want to do with it," says Kevin J. "Seamus" Hasson, president of the Becket Fund for Religious Liberty, which filed an amicus brief in this case. "This isn't a religious liberty case; it's a sneak attack on well-established principles of religious liberty."
Here's my take:
Scarce goods require allocation. Take for example religious holidays and public schools. I believe members of the Summum church should have the right to excuse their own children from public schools for their own religious holidays (within reason). They do not have the right to insist that because public schools are closed for Christmas they should also be closed for a Corky Ra Memorial Day.
For some purposes numbers matter. History matters too. In this sense reality matters, which is why the Ten Commandments are inscribed on the Supreme Court building, but the Seven Aphorisms are not likely to be anytime soon.
