Funny you say that. In school I learned that McCarthy was a fanatic who conducted a Communist Man Hunt that was like the Salem Witch Trials. Infact, I can say that idea was reinforced.
McCarthy saw the danger communism, if left unchecked, posed to America.
While his methods may have been, ummm, extreme, his intent was honorable.
To identify the persons within the communist movement and shed light on the rats.
I'm having a braim freeze here, someone please tell me the name of the man in FDR's adminstration, Asst Sec. of State, who was later identified as a communist.
