The Dixie Chicks had their career derailed with only a nascent Internet in existence. It was never necessary for people to organize and decide collectively something needed to be shunned.

"Cancel culture refers to the mass withdrawal of support from public figures or celebrities who have done things that aren't socially accepted today."

That's a pretty concise description of what happened to the Dixie Chicks after they criticized George W. Bush.

And yes shaming started in the Garden of Eden, and that has nothing to do with Cancel Culture.
