Lamentably, yeah, tribalism does seem to be something we see in humans and less so in D&D races. Just about the only counter-examples I can think of are elves (drow vs not-drow, and that one's being specifically toned down over time), and gith (-yanki vs -zerai, and that one's a deep ideological fissure closer to a religion.) I guess there's some implicit anti-chromatic racism amongst dragonborn sometimes? But at least in their 4e incarnation, they were mostly just various earth-tones, not actually metallic or chromatic.If we were going for a novel, instead of something we wanted to put widely in the minds of players of all ages in game, would two more be:
Tribalism (xenophobia, racism, social hierarchies)
Breeding isn't stopped by the tribalism
In a sense, it's sort of the flipside of the fierce pack-bonding instinct. That which is genuinely NOT part of the pack is a threat to it. And when those "this is bad" pattern-recognition senses kick into overdrive...well.
"Now this is the law of the jungle, as old and as true as the sky,
And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree trunk, the law runneth forward and back;
For the strength of the pack is the wolf, and the strength of the wolf is the pack."
I think of this often, though in relation to Destiny 2 and its lore, which is sadly significantly better than the actual game. Genuinely philosophical evil, that actually thinks and argues, is so rare in fiction.
