Only in the mind of the player, as far as the code to write it is concerned, it's the same thing. If it was said that the "teachers" were child pornographers and the "students" were suicide bombers, with out any change to the graphic layout, some would be all "guns ablaze!" in this mod. Bin-Laden is the politically correct "bad guy" of the times, as was "Saddam" in times before, games about killing incarnations of them are fine and raise not a single blip on the moral radar. The maker of this mod isn't advocating killing innocents (based on what I read in the interview) and I'm not saying he is some kind of shock activist with some kind of message, what I'm really curious about is how quickly one can change their view, with the toggle of a texture and some re-written text.
