Well I have yet to see any major condemnations through broadcast and newspapers.
Would you have noticed if they had? Have you been actively looking for it, or awaiting it? Chances are it's already happened many times.
Also, many moderate Muslims have complained that the US media is only exacerbating things by giving the extremists all the attention. As I've been trying to say all along, it's the whacko minority that always shouts the loudest, and thus gets all the attention. It's exactly the same in any society.
And who is the Muslim equivalent of the Pope, exactly? Also, the Pope only represents one section of Christianity, which contains a moderate-extreme axis within it too. It's the same with Islam, except that none of the sects have a leader on the same scale as the Pope.
Hopefully the irony of your first and last sentences when put together is not lost on anybody else.
