tim... let me be the first to say that you have a fantastic set of in-laws!!! hell, i should've married your wife....
weighing in on the other issue, i think the true difference lies in humanity of intent. where someone like fawkes, che guevara, even the very founders of america itself operate(d) under the theory of rising up against unjust conditions and improving the lives of at least a few, those like hitler, osama, saddam, and others at their core are self-serving sociopaths with little or no regard for the human condition as a whole, and absolutely no belief in the value of human life. i think there's a very fine line between revolutionary and terrorist, but history shows the line to be very clear.
