If they’d just DNWed “race-bending AUs”, I wouldn’t have noticed at all. That’s a totally normal and non-wanky DNW! But the way it’s phrased makes it sound like it’s fine to make all the non-white people white, but you MUST keep all the white people as-is, which… yikes. I want to be charitable and assume this happened because the requested characters here happened to be white, so the reverse wouldn’t come up for this exchange, but the horrifying dom/sub rant doesn't leave me feeling very charitable. :/
