Downvoted because, while I agree with the content of the message [1], I object to the way it was delivered, which seems to me to imply that an acceptable reaction to those who make the mistake is, "That was so stupid, I'm not even going to explain why you're wrong. Just do what I say." That they're worth little enough to the community as to be acceptable targets of ridicule. If I had been publicly admonished in this way, I would feel alienated.

[1] Frivolous use of the word "rationality" and its conjugates in post titles needs to be curtailed and prevented.

Edited to clarify. (Thanks, wedrifid!) Original text follows for context, but please disregard.

Downvoted for status signalling at the expense of newcomers who can reasonably be expected to not have read A Human's Guide to Words yet, without at least linking to an accessible explanation for those who might misinterpret the joke.
