I agree, which is why I find Chambers' review of Atlas Shrugged so over the top (he accuses her, in so many words, of wanting to send her ideological foes to "the gas chamber").
I know it’s almost funny, but I think that perhaps Whittaker Chambers completely missed her point of view because of A) her atheism, and B) his time and place. I think he was so completely immersed in it, that he couldn’t see the forest for the trees.
