I knew Iranians in college. They were good people, good Muslims, but not terribly serious about it. They didn't drink, or date. But they went to dances, and parties. They hung out with the rest of us. When a professor asked Hossein (Usually called Hoss.) if he'd been to Mecca, Hoss responded " Hell no! You got to kiss a lot of stuff good bye when you do that!"
The Iranians I knew knew how to enjoy themselves. They subsituted caffeine and sugar for alcohol, but they were serious partyers. I always wonder why Iranians put up with the mullahs. I keep hoping they will stand up and drive the fanatics out. They won't do it if we invade.
