ISIS Beheading

I added the Knights Templar because despite not existing for centuries they've often been held up as a criticism of, and argument against, Christianity... and even then, they were formed with the intention of protecting people (albeit fellow Christians) and the actual historical Knights Templar were less bad than a lot of fictional portrayals of them (such as their portrayal in Assassin's Creed).

If they had nothing to do with Christianity, why do they get used in criticisms of Christianity (albeit less often than events like the Crusades or other groups like the Spanish Inquisition)?

Gotta admire his ambition for trying to do a head transplant, though.
