“Indians” don’t merely exist as a cultural concept in spaghetti westerns, and even if they did, fantastic racism is still racism.
Buuuut for fun, I’ll engage with your pivot to definition, and I’ll just add this quote for context that appears in the link you provided. Juuuust below your listed definitions.
Dictionaries are often treated as the final arbiter in arguments over a word’s meaning, but they are not always well suited for settling disputes. The lexicographer’s role is to explain how words are (or have been) actually used, not how some may feel that they should be used, and they say nothing about the intrinsic nature of the thing named or described by a word, much less the significance it may have for individuals.
Isn’t that amazing? “They say nothing about the intrinsic nature of the thing named or described by a word.” Your authority explicitly states that they shouldn’t be used as an authority in this context! Remarkable…
And now, in addition, I’ll provide the rest of that passage, which is also the absolute end of me interacting with you in this manner.
When discussing concepts like racism, therefore, it is prudent to recognize that quoting from a dictionary is unlikely to either mollify or persuade the person with whom one is arguing.
Not only not meant to be used as an authority, but also unlikely to settle any dispute you might have about the word.
I’ll take their advice. You can reply however you like- my interest in this conversation has vanished. Hopefully someone more patient will come along.
