ulvy by the logic of your first post
I find my hispanic wife prettier than most middle eastern girsl I must be racist?
I had an asian employee once, cried racism all the time I "singled her out" because she was asian had nothing to do with the fact she called out at least twice a week. It wasn't until she learned I had married a hispanic girl(I'm white) she realized I "wasn't racist"
Thinking one race is prettier than another isn't really racism it's just a preference liking apples more than opranges doesn't make me bigoted against oranges.
Tolkien never compares races like that anyway an Orc isn't a "different race from men" Their literally a different species. orcs are representative of evil NOT black people. You're searching for something that isn't there.
and to end on a fun note
Avenue Q- may be offensive to some people proceed with caution
