There are many practical reasons to do this, I just wasn't clear on the race-related reasoning for blacklist/whitelist, as these words don't have those etymologies.

The color black is associated with many non-racial things that we do deem negative, things like death with black clothes at funerals, things like the darkness being the absence of light (sunlight is brighter/whiter), being blinded, where we do mostly see black. None of those things are racial, what should we do about all those?

Perhaps a better change is to stop associating our skin color with those words which are clearly inaccurate, and serve absolutely no useful purpose.
