We think that Matthew Ehret has some very interesting things to say about the role of Tavistock and the CIA in relation to the counterculture.
However, using the word satanic is a loaded vice word that invites people to think dualistically and moralistically. If satanic refers to Tavistock and the CIA we think it would be better to use secular, rather than religious terminology. If it refers to rock musicians using it the word winds up begin on the same side as Christian fundamentalists. We agree with some of the criticisms of rock music, but rock music also had its positive side when seen against the dead conservative culture of the early 1950s.
