I'm fully aware that the Muslim Community Center proposed for Lower Manhattan isn't really an issue that folks outside of NYC (or DC) care all that much about. Therefor, I won't take too much of your time.
Did anyone else wonder why there have not been more court challenges to this project. Since zoning laws and such can be used to encourage or block just about any project it seemed strange to me that the opponents of this project had resorted to: " It may be their right, but it's just not right," type arguments. So I did a little research.
It turns out that in 2000 the then Republican Congress, at the urging of evangelical Christian groups, passed a bill, signed into law by President Clinton, to protect churches from being zoned out of neighborhoods. It's called The Religious Land Use and Institutionalized Persons Act. The law is explained here.
So you see, those opposed can't win in court because of a law that they, themselves, championed. Ain't Karma great!
