That's borderline trolling, and rude. You could simply ask.
Nevertheless, let me mention a relevant fun fact: I even remember there was a research paper (or maybe a non-academic experiment somewhere on Reddit or so, I fail to recall for sure) which says postulating something wrong publicly is way more efficient than asking a question - much more people rush to emerge passionately addressing all the flaws of your opinion in details and with references than when you ask.
