Just a quick google search turned up a bunch of information about Muslims condemning terrorism, and being vocal. Just because the MSM didn't cover it doesn't mean it didn't happen.
Because we can pull a few articles up on google does not mean there are large numbers vocally protesting radical islam. Why are they now out in the streets protesting? Why are they not writing letters to the editors around the country? I'm sorry, but they are few and far between. It may be fear, but what does that say about Islam if there are large numbers who disagree but are too afraid to step up and say so?
The Global Relief Foundation, which has now been shut down for allegedly funding terror, had a ringing condemnation of 9/11 on its website.
The recently-arrested Lodi imams participated in peace rallies with Christians and Jews after 9/11.
Arafat frequently condemned terror attacks. These and other examples of insincerity don't of themselves lead to the conclusion that every other Muslim group that condemns terror is being insincere also, but they underscore the need for their words to be backed up with deeds.
I trust we will soon see a concerted effort among American Muslims to root out adherents of the jihadist ideology from among them. But I am not holding my breath.
