Note well: Chomsky is a radical man of the left and he (1) condemns hate speech laws, (2) the idea that the government should determine what is history, and (3) laws against Holocaust denial. Why? Because is a radical defender of free speech, the most precious foundation of a free society.
But the regressive left these days would no doubt subject him to the most vicious abuse for this sort of defence of freedom of speech, because the regressive left often opposes free speech. Could there be any greater betrayal of a truly free society?
