How exactly is a recognition of the fact that being Caldari is a cultural identity, one that can include peoples from all across New Eden as long as they embrace it and live their lives by it, in any way similar to U-Nat rhetoric?
U-Nats like the Gallentia Primacy are ethnonationalists and Gallente supremacists. That is the exact opposite of what the Caldari believe. Those that hold U-Nat adjacent beliefs belong in the ranks of groups such as the Dragonaurs, Guristas.
Adams can delude himself and pretend he is Caldari as much as I can claim to be the Empress of the Amarr. In the end of the day, though, if society does not recognize such a belief, and the person claiming such an identity does not live their life according to it, it is worthless. Just a shallow delusion existing exclusively in their heads.
