honestly, one of the reasons I think Chomsky was not censured was not only his anti-communism, but also at every lecture he'd get asked "ok what do we do about all this," and after an hour or two of detailed accounts of this system lying, cheating, murdering, invading, slaughtering and all the rest of it, he'd just be like "it's still a pretty free place, you can do anything you want, just do whatever." Meanwhile all the people who really tried to do something are a molderin' in the grave, as they say.
