Well in case you haven't noticed, in the case of Islam, they are the same thing.
The only real barrier to the truth, is believing you already have it. Any idea how we treated the Japanese, concerning their religion? Remember they worshipped the Emperor.
What do you think would happen if a Christian cult decided they needed a prayer call 5 times a day, and asked the army to provide notice and all the materials to observer that? If you think that would actually happen then there is no need for further discussion, you already know everything.
In case you haven't noticed, a lot of American citizens are Muslim and under the Constitution they have the freedom to follow their religion. Strange thing about the Constitution, it doesn't leave it up to you to decide what is regilion and what is politics.
