Your argument was flawed in and of itself. Recent events have amply demonstrated it is not permissible to make fun of the Koran, Mohammed, or Islamic religion in general. I don't really see the pull behind your statement.

Look up some recent history, reference the Danish cartoon that sparked so very much controversey, Theo Van Gogh, alleged Koran mistreatment at Guantanamo Bay, or whatever else strikes your fancy.
