90% of Muslims will agree that Khomenei is not qualified to issue fatwas, and 99.9% (at least) will agree that the individuals who issued the "fatwas" for the punishment of the two girls in this thread are not qualified either. Just because these groups claim to be Islamic authorities and use Islam to justify their crimes does not make the religion to blame, it makes the individuals (and their few supporters) to blame. Similar examples can be found of people abusing other religions by using them to justify their own evils.
But like like other religious apologists you have to resort to moral relativism. Islam
has to condemn the fundamentalists, and vocally, or else it is tarnished with the same stain. It has remained notably silent in regards to this. That is shameful. The Catholic church for years covered up sexual abuses by it's members, and the laity, like yourself bobs, made apologies or said 'big deal, other religions commit such acts as well.' Well, they're paying for such indifference and arrogance both monetarily and spiritually.
See this is the problem when you mix religion, a fairly nice concept on paper, with people. People always fuck it up and behave selfishly. Pointing your fingers at others is no way to clean your own house.
