You didn't mention 'Weird Scenes from Laurel Canyon', Dave McGowan, in which he details how the hippies were actually created in order to discredit the antiwar movement.
Damning with faint praise is only one reason to craft what appears to be counterpropaganda on the surface. Disinfo is every bit as useful as misinfo, and even enabling your enemies to form groups and alliances is a great idea - if you control the heads of the organizations and message.
Dave McGowan was an interesting character, known for impeccable research.
You'd like him.
Thanks!
