Greetings!
As has been mentioned numerous times by many, there is NOTHING legitimate about the SJW's arguments in favor of "Diversity and Representation." It is all political bullshit created by cock-sucking Marxists that want to corrupt everything in Western society.
D&D games have *always* been diverse. Every campaign I have DM'd--and most of the campaigns I have played in from the beginning--decades ago now, from the 1970's--have been diverse.
The SJW's can get fucked. Geesus, these people are such mindless, brainwashed troglodytes! In random hypothetical game world I have played in--just like nearly every gamer's campaign worlds--we have had white people, black people, brown people, and Asian people. Is it verboten to characterize Asian people as "Yellow"? I recall reading numerous books that considered the technical skin tones of Asians as being "yellow"--which is why forever they have been considered the yellow race. I've always thought Asians seem to mostly range from being pale, pale white, to a warm, medium brown colour. Ahh, the various technical manuals that describe skin colours get all into all kinds o crazy shades and variations. Whatever though. And campaigns had lots of Middle-Eastern types of people, too.
However, the huge elephant in the room though, is when you actually think of "Diversity"--all of these various Human traditions and variations--and focusing on them to the hysterical obsession--is really petty and irrelevant in a typical D&D fantasy world. In the typical D&D fantasy world, there are Orcs, Halflings, Elves, Dwarves, and Gnomes as major races. Then, there are numerous other potential races that are relatively common--Tieflings, Dragonborn, Minotaurs, Goblins, Beastmen, Satyrs, as well as Ratmen, Lion-people, Tabaxi, Tiger people, Elephant people, Hippo people, not to mention Insect people, Trolls, Bird people, and dozens of half-races.
How much fucking diversity do you need? All of that seems overwhelmingly diverse to me. It's a wonder that Humans manage to survive at all in such worlds full of diverse humanoid races. Still, the point being, there is enormous variety nd diversity throughout D&D game campaigns. In the face of such enormous racial and cultural diversity, the particular Human varieties seem entirely irrelevant to me. Furthermore, in such an environment, it doesn't seem like most Human communities would be all that concerned about slight variations of Humans, when there are absolute hordes of non-Human races in every direction.
D&D has always had enormous diversity, inherently, in every game world and campaign.
