Islam is dangerous. It is as much a political system as it is a religion. It is imperialistic.
It is a political system ruled by the religion, it is totally incompatible with any other religion or government. Devout Muslims cannot take an oath to the constitution which is necessary to be naturalized or serve in any government position, yet they become naturalized and are elected to government positions.
We may not be at war with them but they certainly at war with us and the rest of the world.
