Yeeeeeah, sorry Arkandel but I'm like... five minutes into that video and I'm going to give myself a migraine from rolling my eyes so hard.
Like, a minute in, he's giving a pitch-perfect recital of the Thermian argument--link to the video that coined the phrase, but for those who don't want to watch a five-minute video, the "Thermian argument" is presenting the fictional in-universe justification for a plot or setting element as a response to critique, as though the speaker was a Thermian from Galaxy Quest. (If you haven't seen Galaxy Quest I award you no points and may God have mercy on your soul, and the Thermians are a species of alien who don't understand that fiction exists, so when they have to deal with a conquering warlord coming to exterminate them, they kidnap the actors of a Star Trek expy to save them. Also watch Galaxy Quest it's hilarious and also legitimately the best Star Trek movie ever made.)
Point is: he tries to brush aside criticism of the racial problems with orcs by citing the in-universe explanation of how the orcs are actually elves who'd been tortured and degraded by Morgoth. Someone who knew Tolkien better, though, would know that this was only one of several explanations he toyed with through the years, although it's the closest that's come to a "canonical" answer. Other thoughts included the idea that Morgoth created the orcs as a mockery of Men and Elves, but that ran into the issue that evil, in Tolkien's conception, can only corrupt but not create. Another was that orcs aren't really alive at all, just matter set into motion by Morgoth and Sauron's will, but that has the issue with how they're presented in the books as individuals with personal desires, grudges, and so on. The thing about being corrupted elves is the best one he came up with, but as mentioned, that runs into the issue that corrupted elves should, then, be redeemable.
What all that word word words amounts to, though, is Tolkien trying to reconcile his cosmology and Catholic worldview with what orcs actually are, which is: something that looks like a person only hideous and inherently evil. (The letter mentioned in the video and the article referenced, incidentally, has Tolkien describing the orcs as "squat, broad, flat-nosed, sallow-skinned, with wide mouths and slant eyes: in fact degraded and repulsive versions of the (to Europeans) least lovely Mongol-types." "Mongol-types," here, being a reference to the archaic racial classifications, Caucasioid, Mongolod, and Negroid. You can tell that orcs are monsters because they look like really ugly Asian people.)
So no, some post-hoc worldbuilding to explain why the degraded and repulsive Mongoloid horde of subhumans are coming to slaughter, enslave, and rape the virtuous Normans and Saxons who stand against them doesn't actually make it stop being some really racist tropes. And then we can get into the D&D presentation of orcs, where they're physically powerful but mentally dim tribal creatures with an inherently savage disposition, lead by chiefs and bolstered by shamans or witch doctors to provide spellcasting ability. Incidentally, Gygax explained to D&D players that killing orc babies was moral behavior because "nits make lice," a word for word quote from when Colonel John Chivington sent the US Army to kill Cheyanne children at Sand Creek, Colorado.
(Oh, hey, and he brings up the Drow, too. The elves who have black skin because they turned evil. Like the Curse of Ham.)
Like, I'm not saying "cancel Tolkien" or "cancel Gygax" (although seriously Gary the fuck), but it's frankly some willful blindness to pretend that the "evil races" in fantasy and D&D don't have some fucked-up relationships to the real world. (This wasn't a discovery made on Tumblr, either. Michael Moorecock touched on a good bit of this in his essay "Starship Stormtroopers" in 1978, and The Iron Dream was written in 1974, with the conceit that it was a classic heroic pulp novel written by Adolph Hitler after his political ambitions didn't work out.)
Okay, back into this... six minutes whining about how someone ate a ban on RPG.net because people were saying to talk to an actual Native American before writing Native Americans into a published setting, and this guy gave a whole thing about how that's hard. Neato.
Two minutes complaining about pronouns. Rock the fuck on.
Okay, cool, and now we're onto PETA... oh he's saying that considering marginalized people who might be in your audience is exactly like PETA talking about how we shouldn't use animal characteristics as insults because he's made the whole argument around a strawman that people are saying that literally no one should ever be offended by anything so "what will the PETA people think" is exactly the same as "is this being racist and will that drive minorities out of my hobby."
Right, fuck this, tapping out.
