‘Virtue Signalling’ may annoy us but civilization would be impossible without it (quillette.com)

Virtue signaling is what pretend heroes do. 100%

This is interesting and admirable to see on Quillete, as their audience is not generally welcoming to the thesis. It's a good look for them.

I thought I would understand what virtue signalling was by the end of this article if there was enough context clues, but I still have no idea what this is supposed to mean. I get the impression the author believes the reader should already know what they are talking about.
