OK, I take back what I said about reading history....maybe. What books/sources are you talking about? Seriously, I'd like to check out the credibility of these claims.

 In this age of Fake News and sketchy claims, I'd very much like to look at these KGB records you speak of to see if they are exceptional or ubiquitous. 

And understand also that many Americans at the time and now still believe that we have freedom of thought to even consider the benefits of a socialist or even a communist system of government. Or is freedom of thought not one of the freedoms we should expect as Americans?
