Why should ordinary Muslims be protesting about Isis in numbers? Maybe the hysteria has been so whipped up that many ordinary Muslims are simply frightened. Frightened of a government that hates everybody in society and funds terror, frightened of prejudiced people who lap it all up, and frightened of what they are reading in the papers everyday. If you were to believe The Daily Mail etc, it is pretty scary stuff. Though I don't for a moment believe it is an accurate picture myself.
I think most people are struggling in a world that has been designed to make people suffer. By the same token children are being abused all around the country and gag orders are being put on care home investigations. You could also ask why don't parents protest about institutional paedophilia in large numbers? Why are British parents not concerned about the abuse of children? It's a scary topic and most people are not outspoken.
Again I wouldn't blame all parents when many are really struggling to survive, let alone get down to London and vent their anger for days at a time. I apply the same to moderate Muslims.
