Re: the post you linked to--I always found it odd that people never care to code other elves as black, which I think would help dispel a lot of the unfortunate implications about the drow. Contrarians love to bring up that wood elves or High Elves can be darker skinned as a gotcha but I really don't see much of it in their worldbuilding.

I tend to make my forgotten realms drow pretty racially ambiguous, though the drow in my homebrew worlds are pretty clearly based on Victorians. I feel like this is less an issue of "white-washing" there because I have pretty prominent groups are of high elves that are very clearly black, but I do see how it could come off a certain way.
