Tbf the only time I can remember the subject coming up recently was a helfer telling an anti they didn’t have legitimate grounds to discuss elves because their character’s skin was too dark.
The vast majority of the time I see it come up it’s been randoms who I’ve never seen before, but there have been some pretty rough racial remarks in these threads by regular posters who have universally been helfers. I don’t know if I’d say only one side has racists, but it does seem a lot more prevalent amongst helfers from my experience.
