I believe that is true. The only real terror attack we had in recent times was a young immigrant who shot up a free speech congress. When he was burried literally thousands of 'moderate' muslims followed him to his grave, in a gesture I can only interpret as honoring his deeds.
The media portayed him as a lone wolf, even though his friends helped him with automatic weapons, bullet proof vests and knives. The friends who helped him didn't get a sentence.
