Noam Chomsky has a point that Holocaust denialism shouldn't be silenced to the level of treatment that society is imposing to it right now. Of course the Holocaust happened and so on but criminalizing the pseudo-history being offered by Holocaust deniers is unwarranted and is restricting freedom of speech. There are many conspiracy theories and pseudo-historical books available to the public and yet we do not try to criminalize these. I do not also witness the same public rejection to comfort women denialism in Asia to the point of making it a criminal offense or at least placing it on the same level of abhorrence as Holocaust denialism.
Having said that, I would argue that Holocaust denialism should be lumped into the category along the lines of being pseudo-history, unsubstantiated historical revisionism or conspiracy theories or whichever category the idea falls into but not into ones that should be banned and criminalize. If the pseudo-history/historical revisionism of Holocaust denialism is to be made a criminal offense, then we should equally criminalize other such thoughts including the comfort women denialism in Japan or that Hitler's invasion of the Soviet Union was a pre-emptive strike.
Edit: This has been a very interesting discussion on my first time submitting a CMV post. My sleep is overdue so I won't be responding for awhile but keep the comments coming!
