There is a problem in the perception of terrorism. Most terrorism isn't islamic (at least in the West). But you wouldn't know that from the media.
For starters, much more attention is paid to Islamic terrorism than to other form of mass murders. Just look how Boston was locked up for days after an attack that killed 3, and compare to the reaction to the regular gun massacre.
Also, since we all know plenty of white but generally fewer Arabs/Muslims, we tend to excuse white terrorists. People like Breivik are written off as loony psychopath, while Muslim terrorists are depicted a sane but dangerous individuals.
Third, the same acts is often describe as terrorism when done by Muslims but not when done by white. A Palestinian killing a settler is a terrorist, but a settler killing a Palestinian is a mere murderer. The Fort Hood shooting has been called an act of terror, but how many shooting by whites have been called so?
Fourthly, no media attention is paid to the "good" muslims. Here in Belgium, we had a group called Sharia4Belgium that gathered a lot of media attention and prompted a lot of anti-Muslim ranting. But no one ever said that the first people to call attention and sue Sharia4Belgium were a progressive Muslim group. I only know it because I know someone who know someone from that group. Not only are most muslim non terrorrist, but the first line of defense against muslim extremists is actually made up of other muslims, because they're the one in the communities. Same when a terrorist network is destroyed by the police, the informants are also Muslims.
Finally, much more attention is paid to Islamic terrorism than to other terrorists. That's why the US focus so much attention on Muslims and so few on right-wing terror group, despite Muslims
only accounting for 6% of acts of terror (That's less than Jewish terrorism. When was the last time you've heard of a Jewish terorrist network?). It's even worse in Europe, where Muslim account for a
whooping 0.6% of Terrorist attacks (although a larger share of death from terrorists).
Back in 2008 for exemple, Islamist commited exactly as many terrorists attacks as the feard
Comité d'Action Viticole, a french group looking to ban wine imports.
Sorry for the rant, I realize this isn't well-written, but I think most of the arguments are there.
