Even more interesting is the source of Chomsky's quote the WT used. It is apparently from a book that is basically an interview by David Barsamian. The book is called, "Propaganda and the Public Mind" (2001). The quote is from page 158.
Be sure to notice what Chomsky said two sentences before the quote used in the Watchtower: "You shouldn’t believe what I say it true."
The context being, don't believe anyone just because they said it. It doesn't matter who they are or what credentials or "authority" they supposedly have. Check it out for yourself!
This is the approach we all should take, particularly in reference to anything published by the WTBTS or spoken by any of their representatives.
