You do realize that you just straight-up insulted Alinsky without attacking any specific arguments, or presenting any evidence, right? Was that for irony?
Alinsky advocated the process of isolating and demonizing ideological opponents. Sorry, I thought the article included that key piece of information. It may have the last time I read it. That is a problem with presenting Wikipedia articles as evidence. They can change at any time.
And, BTW, the Fallacies List article has really grown too big from what I considered its best version several years ago.
Yes, it seems to be missing the part you were looking for. It is referenced in http://en.wikipedia.org/wiki/Rules_for_Radicals , which at the bottom includes the classic line "pick the target, freeze it, personalize it, and polarize it." In general, as that page shows, his approach was in the end nothing more than "The ends justify the means" and the employment of logical fallacies for the consumption of the public has definitely been used by his disciples.
(Yes, he writes some verbiage trying to cloak the fact that he completely believes "the ends justify the means", but in the end that's all it collapses to.)
