If someone were to make a story set during ww2 where a nazi got with a Jew and dismissed the entire thing of the Holocaust, then yeah. I recommend you read sottovoces responses as they do a great job clarifying why people are upset. And if people chose to let this pass by, authors would just get more audacious. The reason kpop artists were blatsntly racist back in the day was cos they had no one checking them or blowing up at them for the "slightest" things. This is prevention.

Really, people are such babies, pretending that things they don't like don't exist. Just accept that slavery was real. I don't really understand why they would bully the author so much?
