“The generation of Weather Underground, Baader-Meinhof, and Red Brigade is about to get their due.”
Those are all organizations from John McCain’s generation, they were not created by the boomers.
It was the Boomers who bought into it, buttressed it, and spread it. Some earlier generation may have created it (invented) but they were few. Too many of the early Boom bought it and spread it like wildfire - they “innovated” it and that is more important than invention.
