See, a 'slime will tell you that islam is the "din al-hanif" or "original religion" and predates the pedophile prophet. It was always here, see, and Mo was only the latest messenger.
Islam has a lie for every occasion, and Muslims are free to use this one when they tell people the are trying to brainwash into their cult - they are not "converting to islam," but actually "reverting" to islam!
It's like that American Indian thing where they say they were always here. Right. They came from somewhere else and pushed other people out. How can you explain those poor Peruvians living on top of a pile of rocks? They moved there by choice?
Islam is the origninal bait-and-switch cult. Be nice, tell lots of good lies, and take over when you reach critical mass.
