That's not much of a difference. How do you think the laws would be enforced, if evolution and other science were outlawed here in the West? To me, the only difference is that one group of whackos (Islamic fundamentalism) is in already power, and the other (our own, home-grown young earth creationism) isn't -- yet. Like you, I hope that the Christian form of fundamentalism, when in power, would be more benign than the Islamic variety. But I wouldn't want to bet on it.
I've said this before, and I'll say it again. The only differences (in principle) among the different fundamentalist movements are: 1) the deity, 2) the prophet, 3) the scripture, and occasionally 4) the language. Everything else is window dressing.
As for the Christian variety being more benign, the historical evidence doesn't bode well: The Spanish Inquisition, hanging of Witches in Salem, MA, and most recently, the murderous behavior of the Christian Falangist militia in Lebanon are not exactly ringing examples of religious tolerance and restraint.
