Nope Big Bill....I still honestly believe that naming ones opponent is a natural state of affairs and I support it in time of war. Once committed to battle its a GOOD thing to dehumanize a bit. It probably makes its easy to pull the trigger.
A soldiers job is at its most common lowest denominator consists of one thing. "killing"
I believe we will have wars on this planet as long as there are people on it.
After the fight is over and one side has won ....then the humanizing begins.
I think if faced with a need to shoot someone I dont know nor personally dislike on a personal level it'd be much easier if I viewed him at least for the short term as an amoeba or a barely animate object.
Your right its always been this way and it always will be.
A wholly apolitical thing as well.
