Seriously, go grab a copy of the book I referenced above. It is one of those rare life changing books, after you read it nothing is quite the same anymore. Stuff you assumed was so all your life suddenly ain't so anymore and you end up wondering just how much else you take for granted as true is also bunk. The winners wrote the history books and since they still control the 'commanding heights of the culture' they still keep most people from questioning their official version. But there really isn't much doubt left that it is bunk. Seriously, if they can cover this sort of thing up ya start wondering if they really could cover up a dead f*cking alien or some crap like that.
Most folks never even knew the Senate threw all of the records under a fifty year seal and fewer still even noticed when it expired. Wouldn't you think that event would have received a little press coverage, even if just to flog the ghost of McCarthy and do a standard issue rerun of the ritiual flogging of all Republicans as 'McCarthyites? But nope, went unremarked except for a few who did notice the date and quietly went to the archives and looked at the original source documents that were behind the whole mess. His targets were almost all actual commies. What he didn't have the imagination to realize was just how many more there were, even higher up he chain of command, including the Senate itself. Sons of bitches nearly won without firing a shot.
