chomsky appears to have had his own self-interest at work in trying to develop contacts with wealthy members of the elite, and particularly wealthy jews. everybody knows who chomsky is, but it's not so easy to give them a call. chomsky appears to have been trying to leverage the contact with epstein to gain audiences with people that would otherwise not have called him back, for professional purposes. that's what the evidence i've seen suggests.
it's hard to know what was going through noam's mind when carol died, given that they had known each other their whole lives. chomsky was a pretty conservative guy, really. the premise that he'd be interested in little girls strikes me as absurd. but i don't really know.
it's probably not helpful to be too binary about this. might chomsky have gained something from this that was worthwhile to him, to his writing, to his audience? if so, what value would have boycotting epstein had, if it meant he lost access to source material?
