U.K. Beheading Shows It's Time To Fight the Doctrine of Jihad
I have no idea what doctrine that author is following to blatantly state that "Sharia-backed doctrine of armed jihad does permit holy war on non-Muslims, specially in the land of the kufaar." As a Muslim I can readily deny his claim, after all I grew up with the Islamic teachings too.
Aside from his vocabulary, which is clearly coloured in a "jihadist" light (much like Fox news) filled with misleading terms like "holy war" and "jihad," the author fails to specify that a doctrine of armed efforts only applies in declared times of war. Much like any nation's current doctrines of war times. This is the distinction that separates civilized people from violent degenerates who will justify anything by declaring war: "it's a war, anything goes." This attitude and mentality is not exclusive to Muslims or any one group of people for that matter!
