To add a silly post I made on Tolkien reddit a while back that I'm proud of, here's me as Tolkien reviewing the George Foreman Grill:

Draining the fat from meat with this electronic contraption, promoted by a shameless pugilist with no discernible culinary pedigree, is simply a senseless waste of time and human comfort. I'd prefer a four man grill where a giant boar is roasted on a spit over an open flame. The boar requiring two men to rotate over a such a period it would require two other men to turn the spit while the first men rested. They would turn the spit in shifts, two man by two man until the boar was sufficiently roasted and then would be delivered to the local magistrate who would eat it whole. -letter 420 to Guy Fiere

To add a favorite quote

"It was Sam's view of a battle of Men against Men, and he did not like it much. He was glad that he could not see the dead face. He wondered what the man's name was and where he came from; and if he was really evil of heart or what lies or threats had led him on the long March from his home; and if he would not really rather have stayed there in peace"

-The Two Tower (of Herbs and Stewed Rabbit)

I can recall and there was a major lack of investigation and therefore right to speak or at least speak with authority. Deep Tolkien investigation is fucking hard. Like next guy down from Shakespeare as an academically accepted author to study. The orc stuff mostly exists in LOTR but his issues regarding the orcs with his creation myth and making basically a race of cannon fodder kinda sucked and came from goblins and whatnot from folklore which had their own issues that he struggled with mostly came from his letters and the things regarding the south and east being colonized by asshole numemoreans is a brief mention in part of the silmarillion which is tough enough to read buy greater detail requires seeking out less fleshed out notes and writings and piecing it together. Peter Jackson technically didn't have the rights to most of this stuff but it could have inspired a more vague reasoning for these guys joining sauron in the films. Tolkien was old as hell and British and I'm sure he had some degree of racism to him, but gotta say, from anything personal or fictional I've read, haven't really seen much. I'd say Jackson had a way more racist portrayal of the subject than Tolkien

Also, my dude wrote the first poem that would spark the middle earth legendarium while in the trenches in the battle of fucking Somme, one of if not maybe the bloodiest battle of ww1, I think he was like 1 of 5 or so from his graduating class to survive the war. He knew the absolute horror of war and it affected him immensely, especially being ww1 where the fighting was pretty ficking pointless no nazis to beat or whatever. So he had an incredibly dim view on war in general.
