Funny how you don't see this thing going on beyond these places, which, yes are largely Islamic, but more importantly are war-torn places where cultural goats are butting heads, outsiders are claiming resources and establishing rulers and supporting cooperative ones, and where social stability is very fragile, which is where you tend to see some of the worst humanity has to offer, such as post-WWI Germany, which blew the gates open for Nazi ideology.
But yet it goes on that the bulk majority of Muslims are just as appalled by this as we are. There are many Muslim scholars who strongly disagree with this behavior and have denounced it as against Islamic law, and there is a massive outcry from majority of the Ummah, yet this all goes ignored as people still insist this "lack of outcry" proves all Muslims are like that. If they aren't responding here, it's because you're all being a bunch of jerks. Do you honestly believe the Muslim at large community here on RF believes such actions, being carried out in the name of Islam, is acceptable?
No one is calling for a Jewish reform, even though there have been Jewish terrorists and the Torah has somethings in it that are rather unpleasant. No one is calling for Christian reform, even though the Bible has many unpleasant things in it. And although anti-Catholicism has been a large part of the American spirit over it's history, no one was calling for a Christian reform as the priest sex-scandal was being brought to public attention. Now, why is it that we can separate Catholicism from Christianity when it angers us, and even better separate the Vatican from the other Catholics, but yet we cannot separate a few rabid dogs from Islam?
