Talking about hell in and of itself is a waste of time because if there is a "God" no one knows anything about him/her or it and they never will, let alone about what he/she or it will "do" about the "lost." But there are people, lots of them, who think hell is real because it fits their kill-your-neighbor-if-he-looks-at-you-funny vision of "life."
And they think they know all about God too. They think they "know" so much that they burn down American embassies to defend their God and his prophet against some half-assed loons who made a fake 14-min movie and put it on YouTube. They think they know so much that they steal land from Palestinians based on Bronze Age myths in their "Bible" that "gives" them the land. They know so much that they bully the gay boy or girl in their high school somewhere in that desert called "Middle America" in order to do their dumb "god's" will. It doesn't matter what label these people claim -- Muslim, Jewish or Christian -- they are all really in the grip of the same delusion: we have THE TRUTH and you don't!
