Anyway, the big ideological conflict within the Left in mid-20th century was between Stalin's approach and Hitler's approach. In Germany, the Fascists and the Communists engaged in many street fights. In America, the Communists thought Hitler was a fine gentleman -- after he signed the non-aggression pact with Stalin. One big Happy Family! Then Hitler invaded Russia and the American Communists hated his guts.
Anyway. the Kennedy family were supporters of Fascism. Old Joe didn't like the British much and he didn't want us to get involved in WWII. Given all that, it is hardly surprising that a strong anti-communist like Joe McCarthy would find allies within the Kennedy family. I have absolutely no idea what McCarthy thought about Fascism, but he certainly opposed the communists -- just as the Kennedys did, right up until Teddy became their patriarch. At that point, the Kennedys went right over to Karl Marx.
Bump
Joe McCarthy continues to be demonized, despite having been essentially vindicated by history. That the Kennedy family was closely allied with him in the 1950s is an ultra-rare mark in their favor.
John and Bobby were our heroes and the people here act like they were total cretins. Both were allies of Joe McCarthy and both often transcended common politics.
I remember when Molly Ivins died and Freepers refused to trash her; even though she was an absolute enemy of conservatism. The loss of John Kennedy was a great loss for my generation and this country, and he was far more a friend than a foe.
