Luke, I'm sorry but poor show. You cannot quote Chomsky as saying the holocaust is "quite certainly real" then say he is denying its existence in the same sentence. Norman Finkelstein has written reams about manipulation, but he doesn't deny it occurred; in fact his parents were murdered by the Nazis. By manipulation he clearly means the memory of the holocaust has been used politically. If I am wrong please provide some more evidence.
