That no one should criticize or make fun of islam seems to be one thing, if you look at the targets they have gone after. I assume they also want The West not to interfere when they create a space for themselves by killing and/or displacing other peoples in the Middle East.
They demand the removal of Western influences from their society, the removal of current governments in the Middle East (and elsewhere), and the establishment of an expansionist caliphate with Sharia law in their place. Terrorism is not their goal, it is their method.
