One of my favorite sci-fi settings is Traveller's Third Imperium, where the Third Imperium is actually pretty chill with the ayys but they absolutely fucking despise non-Imperium humans.
The fucking hivers(pic related) are considered great allies, but the other human subspecies that aren't part of the empire(with the exception of one, but they're an empire vassal in all but name) are bitter enemies that they constantly fight with.
