And in this story specifically, the cyclops is a main story point.

Someone might describe the story as “It’s about a guy who gets lost and fights a cyclops”. If someone describes it as “It’s about a guy who gets lost and fights a black person”, I wouldn’t know what they’re talking about.

I don’t care if there’s black people in historical dramas, but the person responding in the image probably feels like they did such a sick burn, while what they really did was utterly fail logical thinking.
