I've always said that if a Moslem conqueror was marching across America, the first people lined up to kiss his rump and say "there is no god but Allah, and Mohammad is his prophet" would be the fundamentalist evangelicals - because then they would be able, through force of law, to establish their desired state of misogynist oligarchy that oppresses gays, women, booze and popular entertainment.
Its always so much more important to enforce dogma through civil and criminal law than to persuade through example.
...don't forget the "Unintended Consequences"
