Whi he os responding to: "That's not what I meant, though. I said to replace all instances of "race" with "species" in the rules text. I know everybody will just keep saying "race". We all know. Hell, I'll be the first to keep calling it "race".
But the dangerhairs trying to call it "racist" don't get an opening. Because "actually, they're not 'races', they're full-blown species, with their own biological traits unrelated to humanity." Basically, the sci-fi solution. The only sacrifices to be made there are the mutts. No more half-orcs. Fine, replace them with full-blooded orcs. Savage and bestial, as Gygax intended, and a lot more interesting. And no more half-elves. Good riddance, we don't need 'em."
