Actually Sauron was a fallen angel/demigod basically who thought he was in the right, even though he clearly wasn't, and the orcs/and by extension the urak-hai were corrupted elves/mixed with corrupted men. The Easterlings and Haradrim who serve Sauron, were Eastern-Europeans, East-Asians, Turkroaches, and Arabs/North Africans with it said only some of the Haradrim and being from the farthest south being niggers.
Also the Orcs unlike niggers were capable of mining/creating clever contraptions for war so comparing niggers to them is actually an insult to them, and the corrupted hwite folks who were sadly tortured into becoming them courtesy of Saurons Master, Morgoth. I do agree that their mongrelized appearance truly does represent a future that (((they)))

Kinda sad that Sauron and his obviously catholic biased-depicted Ubermensch Philosophy is ironically a far more desirable alternative to the (((people)))
who rule us today. I'd rather even be ruled by the combine from half-life 2 who are at least honest in their brutality than (((our benefactors)))
