I love how you think this is a rational argument, rather than a demonstration of people's inadequacies and reactionary nature.
And you're putting it to literally the first person in the thread who even mentioned the racism/racialism distinction. Racism is an acceptable word for what is being described. In context, the meaning is obvious and inarguable.
Blame me for my inadequate vocabulary, but whenever someone says having difference between elves and humans is racist, even though it's a perfectly good word and carries no negative connotation (I won't argue on the meaning of English words with you), it sounds like an accusation to my ears. Like eradication of smallpox is rarely celebrated as "the smallpox genocide", I feel a bad vibe about the word "racist".
