Rudeness is perfectly acceptable when it comes to preventing the spread of blithe and thoughtless disinformation. I have no obligation to be polite to people who speak authoritatively on topics they know nothing about. I recommend you spend less energy on trying to defend clueless people by policing the tone of the people educating them, unless you think that polite ignorance is more societally valuable than brusque truth.

> Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes.

Rudeness may be acceptable elsewhere. Not here.

Could you please not sermonize or act like a demanding customer? We don't, and can't ever, see everything that's posted here, and even if we could it's not appropriate for moderators to adjudicate on the correctness of any claim. It’s by cultivating discussions between different people with different perspectives that we illuminate topics here. Obviously you have deep expertise on those topic. Great! Please educate people rather than berating them.

This is only a place anyone wants to participate on because we have guidelines and others make the effort to observe them. You've been here long enough to know that. Please don't trash what you seem to have found value in for so long. We don't need you to be "effusively pleasant" or erudite, just respectful.

For the price of all this righteousness you could have provided a reference. Some reference. So that curious bystanders like me can learn from the exchange.
