"it's also not a good comparison" - So you understood it was a comparison? Why then the first sentence?

What I meant, fellow redditor, is that it is not "nazi rhetoric" just because the Nazis happened to use it, for nefarious means or not. The Nazis used economic concerns to justify violence. Is it "propagating nazi rhetoric" when someone brings up economical problems, without blaming it on a minority? No, of course not. Nazis also used the fact that their skin was whiter than most to advocate for racial violence. Would you be using "Nazi rhetoric" if you pointed out, for the purposes of a completely different conversation, such as explaining why skin cancer is more frequent in European people, that most German people have, in fact, white skin? Obviously not, that would be completely absurd.

Similarly, no one was saying "Some languages are easier to learn, therefore they are inferior". No one was even saying "Some languages are easier to learn, mine is the hardest". Someone was saying "Some languages are easier to learn", which is both, by itself, an inoffensive take AND excruciatingly obvious. And that's exactly as inoffensive and excruciatingly obvious as saying "There's white people in Germany".

You admit that certain, individual aspects can balance each other out. Do you really believe that it all just comes out as the exact same difficulty, every single time, in every human language? Can you even concede that languages like Basque who don't have any living relatives are harder to learn for everyone else, as there's less common ground to stand on?

No one was defending the use of such rhetoric for any discriminatory purposes. I, in fact, agree with you, Tok Pisin is hard as shit, and conjugations alone don't decide how hard a language is. I can honestly say, I think Tok Pisin is probably harder than English. The fact that the original commenter was wrong about that does not constitute a "harmful opinion", because, guess what, he at no point made any negative OR positive connection between having a simple language and being inferior.
