If they had not been applied with misguided negative intent, now laden with racism after decades of colonialism and genocide, would it matter if you called your Orcs that live in mud/stick homes, primitive? Can we describe a FICTIONAL group of beings which are distinctly not human, as savage, or brutal, or are these things now forbidden simply because someone applied the words wrong before?
Can we have a society which is seen by some as lawless, or because that was falsely used to describe a real peoples, thats now simply not to be done?
TLDR: Are we as thinking people able to identify when something was wrong before, and understand that it's use in a fictional sense, is not the same as when it was wrongly used before.
