Actually it was Simon who I quoted.
However the point still stands since the main thrust of this thread has been the fact that ISIS are not a rational political force and the strawman that western liberals do not accept that fact.
ISIS also kills Sunni Muslims who transgress Sharia law, and kills Sunnis who reject ISIS. Just because ISIS kills other Muslims doesn't necessarily make it un-Islamic. Muslims have been slaughtering Muslims of different sects for over a millennia.
So have christians, I assume that you don't take the same extreme view about christian extremists? The point is that the actions of ISIS tell a very different story to the simplistic explanation given in the OP and understanding and accepting that people (especially criminals with no respect for human life) might have motivations other than the ones they admit to.
But what about Abu Sayyaf? It is a terrorist group based in the Phillippines. It recently killed two hostages - John Ridsdel and Robert Hall. What Western foreign policy prompted this?
What about them? Have I claimed that western foreign policy is to blame for all terrorism? No, I said it was a contributing factor in the example I gave. Please don't misquote me again.
The second takeaway point for this thread made by supporters of the OP is the conflation of mainstream muslims and ISIS.
You stated that the only good jihadi is a dead one, how far do want to perpetuate the violence? Because the western world is never going to be able to kill all of them. I can't see any difference between your rhetoric and theirs other than the fact that you are of course an armchair hawk.
