Frankly I believe that most "Moderate" Muslims are afraid to speak out, since to do so would be to invite Fatwa upon themselves. They know there are hundreds, if not thousands of Radical Muslims in the US who would joyously slice their throats for speaking "blasphemy."
When so many of the Moslems sects advocating the extermination of the USA and it's people, maybe we need to follow Reagan's saying: "Trust but Verify".
Turning a blind eye to the Moslem teachings is stupid. Any Moslem sect that doesn't advocate the overthrow of the USA should become more vocal in their opposition to the terrorists.
