Then it is even more bogus. It was already pointed out, no one owns a culture and thus no one has more rights than others to use said culture in works of fiction.The concept of cultural appropriation is not about "being equipped" or "being an expert". It's not a discussion of expertise or competence, and a suggestion that it is indicates that the speaker doesn't understand the nature of the concept they are arguing against. You gotta know what it is before you start arguing against it.
