There is an election-year political showdown brewing over the controversial idea of building an Islamic mosque two blocks from ground zero. Some say it besmirches the memory of the victims of 9/11. Others say that it is private property and the owners should be free to do with it what they like. I believe the anger over this mosque is a continuation of post-9/11 thinking that puts security over civil liberties. Last time I looked, freedom of religion was still protected under the U.S. Constitution.
