There's really two issues here. Firstly, I meant "killing innocent people" to refer to people who are innocent of anything that anyone routinely refers to as "terrorism," like children. Secondly, I have purposefully tried to leave out my own personal views on what constitutes "terrorism" and what constitutes a good response to it, because like you predicted, I'm probably not going to be convinced. But the first point still stands.
I'm deliberately not challenging any perspective you might have on the "global war on terror" and instead trying to sidestep it for the sake of discussion with an isomorphic but distinct alternative issue.
