What a bunch of crap. So legions of left wingers are arguing their innocents? And all this writer can come up with is some right wing freek that did a "study" and half a sentence from the great Eric Foner? And Foner's half sentence is no dobt taken out of context. I don't ever remember reading anthing about their guilt being in doubt. There were questions about Ethel being snuffed out, but that's all.
What this is is an attempt to make McCarthyism seem like not a problem, like no big deal. Perhaps this writer should track down the names on McCarthy's list of 205 members of the communist party in the state department---oh, that's right, he never made that "list" public.
