being an agnostic type guy, i reckon i'm in that trap you describe - in the grand sense there is no right and wrong, just weak and strong - it's a fucked state of affairs that really is best dealt w/ though a combination of strong drink and wilderness wandering
obviously there were other ways to get the usa's attention beyond the 9/11 approach - i don't know if any of them, including the 9/11 way, would work. certainly 9/11 was stupid and ultimately pretty damn counterproductive for the evil-doer's aims.
tvash, you forgot osama's demand that the usa accept islam as well while the 2 demadns you listed sound reasonable enough, i don't think homeboy was the type that could much have been reasoned with, do you?
