Weird that you would give a man in that situation "the benefit of the doubt", honestly.
The man knew about the sexual abuse, didn't think it should be exposed, & palled around with these folks in settings where this abuse was happening. Whether or not he physically touched one of Epstein's victims, he participated in their abuse.
I don't care what good ideas you think Chomsky has had. He's a piece of shit & a traitor to humanity
