This recently happened in Afghanistan. Muslim woman gets in a little argument with a muslim man, because she thinks he's being un-islamic for selling verses of the Quran on the street. He starts shouting out -- "This woman is an American and she has burned the Quran."
What happens next is beyond mental.
Hundreds of superstitious backward thinking savages turn up ("educated" students, shopkeepers, coppers (who do nothing) and whatnot). They not only torture her to death but drag her body through the streets - whilst naturally screaming "God Is Great" - stone her, run her over and then set her on fire. Poor funker is dressed in claret long before they finish her off.
Her parents, for their own safety, have to go on TV to say "She was mentally ill."
God Is Great!!!
