Most/all of your examples have to do with the actual color black.

afaik "blacklisting" comes from the black binding of the book that usually contained the blacklist of a merchant, apparently also employers.

How do you think it came about?

In the English language, she wrote in 2004, color is “related to extortion (blackmail), disrepute (black mark), rejection (blackball), banishment (blacklist), impurity (‘not the driven snow’) and illicitness (black market).”

You thought you were joking, weren't you? The latter link might be sarcasm, but at this point, it's actually hard to tell.

The point isn't to proof that these words are bad, the point is that people have already called for banning these words. 5-10 years ago you would have had similarly "bad" sources for banning blacklist et al., and yet here we are.

They can be wrong now and 5-10 years ago. Something that stupid getting traction doesn't make it more valid
