Excellent question. Hypothetically, could it be that when those that are creative enough to paint a picture of what these agencies really represent, it is as if they are looking into a mirror of truth and hate what they see?
History tells that the Soviets targeted creative people, principally writers. There is a kind of logic to that in that some writers were notable dissidents.
Hitler’s regime was well into book burning. There it seems to be a general vetoing both of thought and rewriting history.
One wonders at the fate of Ernest Hemingway. And others. The assassination of John Lennon. Last year Patrick McLaw, incarcerated in a mental institution for writing Science Fiction and complaining of persecution. (Seems he was right about that ).
But why would the state/intelligence agencies target creative people, bracketing them in the same category of relevance for attention as terrorists? Why would the state feel threatened by musicians, writers of fantasy and poets?
