The most direct analogy in the modern era to the Islamic fanatics would be the Ku Klux Klan. And in more historic era's, the Inquisition, and the Crusades (which were a lot more instituional than Islamic fanatism)

I think the rest of this clip should be shown…

Lets play devils advocate on the soldier who can't kill all the muslims… An islamic extremist/terrorist CAN kill all the christians and justify it religiously.  No worries though, this kind of thing takes critical thinking skills and we all know how poorly the public education does for the citizens of this country.  Pathetic attempt on Gotcha media's part, where's the rest of his thought? what a bullshit clip.

Yikes.
