Even forgetting that many languages have exactly the same construction ("black list") with the same meaning, the thing you do as a non-native speaker with an unfamiliar word is to look it up in a dictionary, or guess its meaning from the context, not try and run some inverse etimology on it.
I mean, for years I understood what "paste" meant (as in "copy and paste") and used that word without having any idea about "paste" being some sort of glue. I still have no idea where the word "parkway" comes from, but understand the word and use it. (If I were to guess from its parts I would arrive to something like a "garden path":))
2. The usual reason given for not saying "blacklist" is because of supposed racism. Your argument is a new one, and seems to have been produced post-facto. Your comment is sophistry.
[edit] Removed some scathing remarks.
I'm not arguing for the removal of the word, I don't know why you think I am.
you mean you white-washed some remarks?
aha!
;)
German is pretty close to English though, so I guess your argument could still hold for other non-related languages.
EDIT: the replies I received to this comment are pretty shocking to me. I'm not arguing for the removal of anything, I am only listing one issue with blacklist that deny-list doesn't have. Anything you're reading into my comment beyond that is your tribal identity projecting its insecurity.
