I don't think that comparing religious fundamentalism of american christians and of islamists is fair. "Fags must die" demonstrations are a long way of overturning governments and genocide.
I'm not comparing them. I'm saying American religious fundamentalism is an impediment to openly opposing religious fundamentalism and anti-equality of the sexes religious doctrine elsewhere, comparable or not. Nonetheless, except for the overt calls for genocide (ours believe The Eschaton will take care of the Jews), you might have picked better examples of differences between the two.
