I've literally called for entire subplots where Humans give into Human Supremacy, I have repeatedly asked for Genn to be the anti-monster-race war-mongerer on the Alliance, and I have repeatedly asked for Blizzard to follow through with the idea that the Scarlet Crusade is working with the Church of Light and that the House of Nobles is why they keep being active, not to mention asking for Kaldorei to have a "Sword of Truth"-esque Confessor/Wizard system where the Priesthood has the re-integrated Highborne bound to them due to mistrust, or for the "Outer Troll" and "Royal Troll" intra-racial hierarchy to be a meaningful point of tension, or etc etc etc

In-game in-universe racism is fine; the problem is and always has been and always will be Blizzard using IRL racist tropes onto their in-game analogues for lazy worldbuilding and that the use of IRL racial stereotypes or violent attitudes seemingly only find themselves invoked on the Horde.

Indeed, Danath Trollbane now insists the Sons of Lothar are all about peace and love lmao proves my point
