Fourth—and this may be most important—he makes people stupid. In this sense, he’s more like a cult leader or a New Age guru than an intellectual.
He allows people to be comfortable with their prejudices and their hatreds, and he undercuts their ability to think in a critical manner. To an extent, this has to do with his use of emotional and moral blackmail.
Since he portrays everyone who disagrees with him as evil, if you do agree with him you must be on the side of good and right. This is essentially a kind of secular puritanism, and it’s very appealing to many people, for obvious reasons, I think. We all want to think well of ourselves, whether we deserve it or not.
There is an intellectual side to this, as well. You see it clearly in his famous debate with Michel Foucault. Chomsky says at one point that there is a moral and ethical order that is hardwired into human beings. And Foucault basically asks him, why? How do you know this hardwired morality exists? And even if it exists, how can we know that it is, in fact, moral in the first place? We may feel it to be moral, but that doesn’t make it true.
Chomsky’s answer is essentially: Because I believe it to be so. Now, whatever that is, it isn’t thinking. In fact, it’s an excuse for not thinking.
Ironically, Chomsky later said that Foucault was the most amoral man he ever met, whereas I would argue that Foucault was simply pointing out that Chomsky’s “morality” is in fact a form of nihilism.
I think people come to Chomsky and essentially worship him for precisely that reason. He allows them to feel justified in their refusal to think. They never have to ask themselves any difficult questions or provide any difficult answers. It’s a form of intellectual cowardice essentially, but I’m sure you can see its appeal.
