I noticed major failures to put language in context. For example, "whitespace" isn't racist: there are fundamental physical reasons for paper, vellum, papyrus etc. to be approximately white, and there's no reason to think it refers to people.
If so many words assign connotations to "white" and "black", indicating a deeply embedded metaphor, perhaps the solution is simply to stop using such loaded and inaccurate word to refer to skin color? They are trying to boil the ocean to preserve a silly convention that was probably racist to begin with.
