In my opinion whether McCarthyism was justified or not is entirely subjective and children should not be indoctrinated to take a particular view. What they should be learning is that modern historians generally agree that McCarthyism had a pretty strong basis in reality and many of the accusations made, in retrospect, are now proven to be justified. As far as I know, every single former KGB agent that has commented on McCarthyism has said it was anything but delusional. They will, however, admit that at the time, it was part of their job to discredit the movement.
