Your interpretation is horribly skewed.
First, you presuppose that the people answering your poll would all be free to shoot whoever they prefer. They wouldn’t. The vast majority of humanity are followers who will never decide anything for themselves at all. They’ll shoot whoever they’re ordered to shoot. So any Matari, for example, who want to kill the Amarr will, if ordered to, shoot Caldari first if the current political alignment goes to war. This is especially true when you consider that the Caldari Navy is more modern and better-maintained than the Golden Fleet, even if the Imperial Navy is larger.
If the action shifts to larger ships… you’d definitely see the target-calling focusing on Caldari and Matari hulls, especially with neut pressure, as the shield ships are seen as being easier to break (how true this is is a matter of some debate among certain segments of the Egg-set. I’ll not get into it now.)
Nobody is going to drop into the middle of it and just start shooting randomly, either (kill everyone). They’re going to look for the weakest set of targets, the ones they can pick off easily. That’s either going to be the people already being shot at first (which, if we take the example above, aren’t the Amarr), or simply the logistics wing of whatever fleet appears to have the fewest.
And if you seriously believe tha State is going to even consider ‘unity’ against the Amarr while the Gallente Federation maintains any presence on their homeworld, and tensions between the two remain high enough that the State closed the border to baseliner traffic just this year… ugh.
Really, if you conducted another, identical poll, and included ‘Yellow Parasol’ on the list of ‘who do you want to see die most?’ you might not like the results so much. Capsuleers don’t give a damn who we kill. Given the choice, most of those maniacs would opt for ‘nursery ship full of orphans and infants’ over ‘someone who can fight back’.
