"Muslims are afraid to speak out and feel separated from the society they live in,...People feel uncomfortable at work, because colleagues question them.''
If they felt like saying the right things I don't think they'd have need to fear, if they had the right answers I'm sure their co-workers would be happy to hear them.
This is why we fear the moderate Muslims too, they go into the "Don't blame me, I didn't kill the guy" mode, it's almost always that, never a full throated denunciation of the Islamofacist violence.
HEY MODERATE MUSLIMS - WE CAN'T HEAR YOU YET!
You say you can't hear the moderate Muslims. Partly this is because they are the first to be killed for expressing their views about the extremists.
A Muslim who worked on the film was also threatened. Maybe we should see this movie.
