Also, as has been pointed out, Islam is much more than a religion. It is a complete socio-political system which is ABSOLUTELY incompatible with our Constitution, not to mention freedom and common sense.
If Islam is totally incompatible with our constitution then why should we be expected to let them immigrate here? Isn’t our president required to protect and defend the constitution of the United States, so help me God? And which God applies (in Obama’s case)?
