This is getting tiresome. Rakesh, you are too intelligent to foul things up so completely with such sloppy analysis, so I'll graciously assume you've mistakenly taken a few too many painkillers left over from your basketball injury.
First, he is not "defend[ing] his right to defend Faurisson". His right to defend Faurisson is not at issue, and needs no "defen[se]". He is simply pointing out that a few idiots claimed it was a huge scandal that he was defending the right to speak of someone with whose ideas he had little familiarity, and that this was absolutely nuts.
Second, he does not "reassure us that Faurisson supported the good fight against the Nazis" --- he merely points out, quite accurately, that there is good evidence that Faurisson is not a mere Nazi (as has so carelessly been claimed) and that he supported much more extreme positions ("far more controversial stands") of free speech for those who *could* quite easily be compared to Nazis, and nobody seemed to care much (this is *very* important: it shows the bankrupt hypocrisy of the media and intelligentsia generally, a topic that Chomsky has spent much time illustrating --- so much so that I'm astonished that you could glide over this point so easily).
Third, this parenthetical comment has nothing to do with whether or not his support of Faurisson's rights was "absolute" (an idiotic notion that Chomsky, as well as myself, would reject as absurd) or done simply because Faurisson represents "little actual danger" (a topic Chomsky ignores, quite rightly: would Faurisson be "more dangerous" were he a "fascist" or a "war criminal"? The question itself if simply bizarre).
Fourth, Chomsky's comments are not "irrelevant" --- they were a very specific response to very specific attacks on his stance, and were important to illustrate the selective nature of the outrage against him.
Finally, quite obviously, those with something stuck in their craw are to blame for the confusion, as Chomsky's words are utterly transparent. Only utter fools, or those with nothing better to do with their time, or with an axe to grind (or with a few too many painkillers floating in their blood) could confuse things so easily.
Let's drop this nonsense and get back to more important issues, shall we?
