You fail to separate an actual object from your perception of it.

Not at all; I recognize and admire the engineering and technology of the plane; I despise it's purpose and function.

What about the Spitfire, or the M1 Garand? They were also tools designed exclusively to kill people, and yet, I'm guessing according to your political views the world would have been a horrible place if they'd never been made.

The fact that the 109 was used by the Nazis is largely irrelevant as far as I am concerned - a weapon is a terrible thing, no matter who wields it. Whether the person who uses it is morally justifiable in doing so does not change that.

War is a fact of humanity. Equating it with base murder is just ridiculous.

Killing another human being is murder, whether it is sanctioned by a state or not.

As far as I'm aware no one has ever been murdered by a Bf 109, all kills ever scored by one were in the context of legitimate wartime combat.

Um, wow. This is quite a statement. Let us for the sake of argument accept that killing another human being in a state sanctioned war is not murder.

JANUARY 3, 1941 FOCKE-WULF FIGHTER PILOT BUDDE AND CORPORAL BARTELS ARE OVERHEARD LAUGHING AND JOKING ABOUT THEIR FAVOURITE WARTIME ESCAPADES BEFORE THE FORMER WAS SHOT DOWN IN THE BATTLE OF BRITAIN AND THE LATTER WAS CAPTURED AS BRITISH TROOPS FELL BACK TOWARDS DUNKIRK IN 1940.

BUDDE: “I flew two spoiling attacks. In other words, we shelled ­buildings.”

BARTELS: “But not destructive attacks with a specific target, like we did?”

BUDDE: “Naah, just spoiling attacks. We encountered some of the nicest targets, like mansions built on a mountainside. When you flew up at them from below and fired into them, you could see the windows rattling and then the roof going up in the air. There was the time we hit Ashford. There was an event in the market square, crowds of people, speeches given. We really sprayed them! That was fun!”

The pilot in question was not a ME-109 pilot, but this illustrates the viciousness of the Luftwaffe culture during WWII.

I can abso-fucking-lutely guarantee that a ME-109 was at one point or another used in the unlawful murder of a civilian by the Luftwaffe. Atrocities committed by the German armed forces during WWII were so commonplace in all branches that it's hopelessly naive to believe otherwise.

edit: Oh I forgot this one:

JANUARY 5, 1945 ­Luftwaffe Oberleutnant Hans Hartigs is from a fighter squadron shot down by a spitfire. He reveals his favourite targets...

HARTIGS: “I used to shoot at everything. We liked to go for women pushing prams, often with children at their sides. It was a kind of sport really.”

It's stated that Hartigs was a fighter pilot, so it's in fact quite likely that he flew ME-109s.
