"I can't think of them as humans. They are sub-humans, at this point. Whether by breeding or indoctrination - or by renouncing their humanity."
You're exactly right. And they HAVE renounced their humanity in my opinion.
I have in another post compared the Islamo facists to bad fruit. Islam has shown itself incapable of eliminating the pestilence that has caused its tree to bear blighted fruit. They do need a major crop dusting program now or the world will begin chopping the trees like we do with maple blight. They don't have much time either. The world is not patient with these primitives.
