This video contains some VERY graphic images and audio, please do not watch it unless you are prepared to see and hear them.
Personally, I found the film extremely upsetting. If you would rather not experience that upset, do not watch it.
I do see merit in the argument that the film incorrectly equates all of Islam with violence. In many ways it has the propaganda elements and tone of the same Islamic videos it criticises. Western classical music is used as background, instead of arabic chanting. The most extreme Islamists are used to portray Islam as evil, in the same way Islamic videos portray the West as evil.
One could hold up an extreme version of anything and hold it up as representative, but it is not.
All this video does is encourage the polarisation of views, instead of the compromising of views.
Religion is a curious thing.
