Oh, my. Judge Roy Moore continues to be own best counterargument:
12/1/2001 - Alabama Judge Exhorts Rally On Ten Commandments - Breaking News - Chattanoogan.com: "He said America 'was not founded on Buddah. It was not founded on Mohammad. It was not founded on Confucious. It was not founded on Islam. We don't put our hand on the Koran. We put our hand on the Bible. We were a nation established upon God.'"
I'm thinking they must not get many Muslim defendants in Talibama courts, but I really wonder what Judge Moore would do if one asked to take the oath on a Koran.
