Islamic laws in America?

On November 22 a article was posted about an argument about a ban on Islamic laws in Oklahoma courts. The argument is raised because an amendment was created in the state of Oklahoma which apparently violated the first amendment in the American Constitution in the eyes of the Islamic community.  The main reason for the argument/law suit is that the families that are Muslim want to have their private documents, wills and other documents to be written in accordance with Muslim law. Maneer Awad, who is a leader of the Muslim community in Oaklahoma, thinks that the amendment made Oaklahoma's islamic community a threat to the state.  In my opinion there shouldn't be a law suit/argument about this stuff.  If these muslims want to have their documents follow "Muslim Laws" then how bout they go back to their home country and go back to following their laws.  There shouldn't be a policy stating that its alright to bend a U.S Amendment because their muslim.  So what I'm trying to say is we as a country give you the right to practice your religion, which by the way is the main reason why this country is at war, accept the fact that we give you enough leeway with that and stop trying to bend the United States Constitution to favor your religion.  Americanize or get out.  Sorry if thats too over the top, but I'm just stating my opinion.
