We're talking about terrorism carried out in the name of Islam, by Muslims, and justified using their holy scripture. But apparently it's got nothing to do with Islam. Well, I'm sorry, but just because every Muslim doesn't support it doesn't mean it's not Islamic. People say you can't judge Islam by its followers, but that's like saying you can't judge a football team by its results. Islam is its followers. Because there's no central authority the Koran is open to interpretation by men, who, being human, will always interpret to suit their own cultural prejudices. So Islam is its followers. It's a representation of how they interpret their holy book. And therefore, the only way it can be judged is by their behaviour.
