Is it too much to ask that for just a moment we might be honest about fundamentalism? No matter the tradition, fundamentalism is heresy and an aberration that has nothing to do with the tradition from which it deviated and devolved.
In short, fundamentalist Islam is not Islam. Fundamentalist Buddhism is not Buddhist, fundamentalist Judaism is not Jewish, fundamentalist Hinduism is not Hindu, and fundamentalist Christianity is not Christian. They are all distortions and perversions of the original religion that have moved so far away from anything even remotely resembling healthy religion that they are no longer entitled to claim to be part of those traditions.
