you're applying your own definition of "honor" here and it's a completely western one.

southern guerillas were terrorists too. were they without honor? some were for certain. just like some of those rebels, just like some islamists. but to say that "terrorists have no morals" is really reducing the problem in a way that's entirely too simplistic for me to swallow.

just because you disagree with a worldview or a political stance or because it appears to be in opposition to democratic freedom doesn't make it "immoral".
