That was one of the world's great recruiting pitches for the 7th C. mind. "Uncle Mohammed wants YOU! Enlist in the Horde today. Good pay plus 72 magical virgins if you get killed."
Nobody with the brains of a goat could believe this. A virgin is no longer a virgin once you -- well, you know. It would be a silly lie to say she is a virgin again. Allah does not lie.
The consensus of both sexes is that once a virgin gets past that hump, so to speak, she is changed. For one thing, she thinks you owe her, big time, and she is right. There will be marriage in paradise -- 72 marriages per martyr, plus (as my tagline points out), all those mothers-in-law. This goes on for the rest of eternity, and somewhere along the line, our hero may figure out that this wasn't "paradise" after all.
/polite skepticism
You obviously didn't go to the same high school I did.
Are you skeptical that radical muslims believe in the 72 virgin reward for "martyrdom?"
