First, I was responding to a post suggesting the use of surrogate executioners when we didn't want prisoners, and my response was that at least some wouldn't have fallen into any legitimate 'prisoner' category.
Second, most people who aren't bending over backwards to push moral equivalence understand the difference between civilians who are killed because they are in the way and a three-year old girl who was killed because a person in the same room with her pointed a weapon at her and pulled the trigger.
But that's okay, if you want to view Marines and their actions as equivalent to AQ and their actions, be my guest. I tend to think we are better than that.
Perhaps if you'd quoted the post to which you were responding, it would have taken on another meaning. Standing on it's own, I took it at face value.
