Sounds like Christianity 1500 years ago.
It's now 2004. Christianity grew up and became civilized. Do Christians believe that the Bible should be the highest authority in America?
"Islam isn't in America to be equal to any other faith, but to become dominant. The Qur'an should be the highest authority in America, and Islam the only accepted religion on earth" -- Omar Ahmed, Chairman of the Board of CAIR (Council of American Islamic Relations), San Ramon Valley Herald, July 1998
