I dunno how many Muslims there are on MB and to what level you practise.
Here's an idea, why does the communities of Islam not collectively put out a Fatwa on Bin Laden and Al Qaueda?
Because, if you ask me, they don't represent Islam. If they say they do, cool! Fatwa for you my friend, regardless of what was going on in your homeland you broke the rule of defense and took the fight to countless civilians who weren't armed for war!
