This was the top post when I checked Lemmy this morning.. Mod commented to mark the post NSFW, even though it wasn't NSFW as far as I could tell. Post was locked and had a ton of deleted comments.
The euphemism treadmill, as far as I understand, goes like this;
- Science comes up with a term for something or some one.
- People start to use that term as a slur.
- Science comes up with a new term because the old term has been tainted.
- People add the new term to the list of slurs. 3 Science faithfully obliges by thinking up a new term. Surely, no one will turn this into a slur!
