It's kind of all of the above. State and non-state actors have leveraged pretty much every movement there is to their own ends: civil rights, anti-nuclear, pro-nuclear, anti-Iranian government sentiment, pro-Iranian government sentiment, even jazz tours in Europe which were assisted by US intelligence orgs in the 20th century.

It's not a 'bad' thing and doesn't say alot about the core movements - it just is what it is.
