Source of Chomsky quote

Would anyone know where does the following quote attributed to Chomsky come from?
“If we don’t believe in freedom of expression for people we despise, we don’t believe in it at all.”

I think it’s from this 1992 interview.

Yes. He says it at 16:30.

For what it’s worth, it’s a pretty common notion. Many people have said approximately the same thing. Probably the most famous version of this is usually attributed to Voltaire, although actually it’s a paraphrase of his ideas that a biographer created. The quotation attributed to Voltaire is “I do not agree with what you have to say, but I’ll defend to the death your right to say it.”:
