If you are confronted with an assertion, there is a short way of getting rid of it, or, at any rate, of throwing suspicion on it, by putting it into some odious category; even though the connection is only apparent, or else of a loose character. You can say, for instance, "That is Manichaeism," or "It is Arianism," or "Pelagianism," or "Idealism," or "Spinozism," or "Pantheism," or "Brownianism," or "Naturalism," or "Atheism," or "Rationalism," "Spiritualism," "Mysticism," and so on. In making an objection of this kind, you take it for granted (1) that the assertion in question is identical with, or is at least contained in, the category cited—that is to say, you cry out, "Oh, I have heard that before"; and (2) that the system referred to has been entirely refuted, and does not contain a word of truth.

The philosopher Arthur Schopenhauer documented these tactics humorously in The Art of Controversy (Chapter III):
http://ebooks.adelaide.edu.au/s/schopenhauer/arthur/controve...
PG advocates for controversies that help find the truth. Thus he makes a difference between fallacies and real arguments. To Schopenhauer, real arguments are actually fallacies, because mere humans have other goals than the truth. Ironically, in http://www.paulgraham.com/philosophy.html, PG followed Wittgenstein in that “most philosophical controversies are due to confusions over language”. In a philosophical context, at least, this should lead to a similar conclusion as Schopenhauer's.
Now, whether the case of philosophy should be extended to the rest of controversies is an interesting question. My answer would be yes. I wonder what PG would say. The fun part is that, whatever he says, Schopenhauer will still be right (look: he doesn't care of the truth, he just wants to win the argument!). That's the whole fun of controversies about controversy...
