Americans are having a hard time discussing the problem of Muslim immigration and assimilation because Islam is not just a religion; it’s a whole way of life, civil and spiritual.
The First Amendment was written because Christians of all denominations believed that while people’s religious beliefs are the basis for the law, no one Christian group should be supported by the power of the federal government. After all, that’s why many Americans had fled England.
Islam, according to many Muslims, rejects that principle and declares that all authority belongs to Islam. It’s as though Catholics believed that the pope should be the ultimate authority for setting the fine you have to pay if you get a speeding ticket.
