Islam is a political ideology masquerading as a religion. It is in direct conflict with democracy.
In order to become a citizen of this country, one must swear to obey our laws and constitution.
However, if one follows the Koran, this would not be possible.
As an example, women under Islamic law are relegated to second class existence. Under Islam, no other forms of government, religions or lifestyles are recognized or should be allowed to exist. It is for these reasons that those who adhere to these principles cannot truthfully take an oath of allegiance to the United States of America. One cannot serve two masters.
