Saying that lotr is multiracial because different characters are different races in universe is missing the point. No black kid is gonna look up to Aragorn and think "he's just like me". Also claiming gender diversity because of one character (and another that had one moment of significance that still could have been cut without much impact on the story resolution) is wild.
I love LOTR as much as the next guy but I can admit it does have somewhat of a diversity issue.
