If I had one wish, it would be that we would all give up that rude “citation needed” trope. I agree with you, yet that’s such a childish way to argue that it hurts the point. Just have the confidence to say you don’t agree!
What I mean by that is more than “i don’t agree” - it’s “hey, it looks like you asserted an opinion as fact”.
I’m pretty sure all ways of saying that come off rude. Sometimes rudeness is irreducible, and I think this is one of those times. I like “citation needed” because to me it seems like a playful version of rude rather than a serious version of rude. Shrugging emoji
