Sketie,
Whoever succeeds in framing the story wins. The way you are framing it. A Muslim wakes up in a vacuum to slaughter a random victim, then goes back to his nap. Looked at in isolation, these acts are pretty evil.
There are good explanations(not justifications) for why these Muslims are doing what they do. Personally I think they are nuts. Yet ultimately, it comes down to how you are wired.
What's happening in the Middle East is a war for control of resources couched in favorable terms by the participants. The best way for the US and Britain to advance their point of view is to reduce it to a caricature based on events within the conflict.
