Why do you hear about Islamic fundamentalists when no one reports on the Christian fundamentalists?
Christian "fundamentalists" don't blow people up or kill innocents because they disagree with what they believe.
Christian "fundamentalism" simply means going back to the basics of Christianity as taught by Jesus. Islamic fundamentalism means going back to Mohamed's original method of spreading his religion, which was to conquer by violence those who would not accept his new religion.
Remember Waco, Texas? The Christian Davidian movement?
Christian fundamentalists who cause harm to innocents are reported on and are dealt with.
