Words can convey negative connotations. Why perpetuate negative colloquialisms that serve to preserve hierarchies of world order? “Third World “ is a constructed designation meant to oppress. Stuff matters, even if it doesn’t to you.
I never said it didn't, this just isn't the right place and in this context it does not matter. It's a term we all know the meaning of and that's what's important.
I wouldn’t say I’m sorry for making you think about the context behind the meaning of words, but because you have had to spend so much energy on this, I apologize.
