Literally no one has ever said that black dragons being evil was racist. And the groundwork for redeeming the black dragons was begun several expansions ago, so the idea that this is suddenly happening now because the SJWs are coming to ruin all the video games is just utter nonsense.
Of course, this is end-of-expansion leak season, so part of me is thinking *maybe* this was a troll post and it's not actually serious.
