Yeah, its tough to understand how people think of a word on a case to case basis. Everyone will have different connotations. There is murkiness that exists as part of its use as a noun or an adjective.
My point of erasure relates to making the use of Hawaiian as a noun specifically relating to anything native Hawaiian.
The football thing doesn't feel entirely on point for me, an analogy of Europeans seeing Tex-Mex and calling it Mexican food seems closer to the idea. It is technically right, but some people from Mexico would disagree with that being _real_ Mexican food.
