Hvis hun ser på seg selv som norsk, så har ikke jeg noe problem med det.

We should let people identify with whatever they want. Identity is deeply personal - that's kind of the whole thing with identity - and as long as you don't use your identity to argue for something that's objectively wrong (such as rewriting history to suit it) then it's fine. If someone wants to identify as the same kind of thing as me, I may be flattered or embarrassed or worst case offended, but let's go for the facts, not with the identity.
