We start down that path and we'll end up banning "Paint it black" as a racist song.
The related term is "whitelist," not "redlist." So I can understand why people might believe the pair has racial overtones.
To my mind, thinking that "blacklisting" has racist connotations because we all African people "black" also, is a similar kind of confusion.
Edit: to clarify what I'm trying to say. The fact that "black" is in "blacklist" is a coincidence and nothing to do with racism. Same as the fact that "his" is in "history".
Which is funny in itself. "history" is sexist because it's male, so let's do some affirmative action and make it sexist in the other direction!
Also, there is also debate about the 'redskins'.
I'm sorry, but what? It's not like you're calling the CEOs/managers "masters" and the rank and file devs "slaves". It's literally a term assigned to an inanimate object.
So you want everyone to forget racism exists? (Because it does BTW).
