Islam is utterly unconstitutional at both the national and state level. There is NO place for Islam in America. It is a totally unconstitutional political system and any school teaching it should be shut down until remedied, and the administrators charged with treason.
This is the crux. Islam is first a political system. Second it is an economic system. Third it is a religious system. It does not pass the test of the US Constitution which specifically separates religion and government.
Government under our constitution may not establish a religion. Islam requires both the form of government and the religion. Islam is in fundamental conflict with the US constitution.
