Fair enough, but terrorism isn't a human rights type issue that people SHOULD care about and fight against for the future benefit of humanity(I speak of terrorism only, not the abhorrent things that go on in their own countries). It's like a jail full of Batman criminals escaped and have access to anything they want. They'll never be caught or apprehended, who do you even target to try and solve this problem without dragging the religion in general into the fracas?
I think its more about not being afraid, that's the goal of terrorism after all, 'don't do this or you could be a target'. Some feel that showing that Islam cannot fear them into placing it above ridicule is important enough to risk being a target, defiance to a bully if you will. If a generation of Muslims grows up in an environment where the Qu'ran is open game they'll be more likely to accept that's the way things work in those particular regions of the world and perhaps breed less extremists that are nationals to those countries.
