I can agree with that to an extent, since organized media can never give voice to everyone. But what about the internet? Where is the "moderate muslims for peace and tolerance" youtube channel? Where are the moderate muslim blogs denouncing violent acts? Well, before i run my mouth, let me go look lol. But I won't be surprised if I don't find much. My guess is that the majority of islamic groups on the net will speak of tolerance and peace in a vague, general sense without denouncing any specific violent acts done by those we call extremists. A kind of "have your cake, eat it too" stance, if you know what i mean.
