After the Fall of the Soviet Union it was found that McCarthy had underestimated the degree of communist penetration - once archives were available. Today the White House has substantial Muslim Brotherhood penetration (and probably a great deal more competing agents, but not to the same degree as the Ikhwan).
McCarthy was *right*. It is the Collectivist Matrix that controls the media that tell you he was wrong. A great book to read is "Disinformation" by Lt Gen Ion Mihai Pacepa. It explains who killed Kennedy and why - and why the Conspiracy Theories are the conspiracy. The media marinates you in Cultural Marxism these days so that people cannot see the truth in plain sight. America has gone off the rails because the Collective (run by a 'political elite') is now valued over the Individual. The Government now feels it can micro-regulate every aspect of your life and treat you like a child. This is Marxism with a smile - and it is what is bankrupting America - yet anyone who opposes the collective is smeared by the media, the academics, the elites and by all the people still in the Collectivist Matrix. McCarthy was right, and is even more right today. Hint: who did Hillary Clinton write here senior thesis about? the same person Obama moved to Chicago to find acolytes of.
There is no substitute for Liberty!
