Morality in fundamentalist circles is merely a blunt weapon used to beat others over the head; it is not something they ever apply to themselves. Their morality is a weapon to be used against others, not a guidepost for their own lives.
"No more violence in the name of God!"
I have decided that what makes fundamentalism so vile is not that it perpetuates bigotry and hate, or the way it lacks authenticity by covering life with a veneer of false piety, or even how it erects (white) man-made boundaries to determine who's in and who's out.
