The term fundamentalist, whether applied to Muslims or Christians, is a largely American construct that implies politically conservatism and, sometimes, extremism. Some groups make no distinction between their cause and their interpretation of the religion. Careful reporting doesn’t assume that religion is the sole basis for political actions. The term Islamic fundamentalist has been used to refer to people who cite Islam to justify political actions. Fairness and accuracy mean attributing political actions to the group, government or party responsible, and not just to the religion, which may have millions of followers with different beliefs. Avoid constructions like Muslim bomb.
