my brother in christ it is a goblin it is a fantasy creature

Yes, a fantasy race one might even say. Tell me, was Birth of a Nation's biggest problem that it didn't make the black people have little cloven hooves and call them satyrs? Would it be above criticism if it merely depicted the revival of the Klan as a way to terrorize and slaughter these dark-skinned, lustful, savage satyrs with no relation to black people?

Because it is a dnd setting and it’s easy to write it that way

I promise you that it's just as easy to write the enemy as being bandits. Hell, even writing them as slimes (an even-more-common bottom-level enemy, #1 along with rats) would be better, since those aren't remotely humanoid but can have basically whatever properties the author wants because they are so literally amorphous.
