It's a Twitter thing now, but it might be useful to understand that it predates Twitter.

E.g., "Goodwin's Law" is supposed to have been coined in 1990, and of course it was a pretty well established phenomenon to earn a coined term.

I know from first-hand experience it was happening on BBS's and newsgroups in the '80s. I would be more surprised than not if it wasn't happening before then too.

(And if you want to generalize slightly, calling someone a Nazi is simply a current way of demonizing your opponent. People have been demonizing their opponents since well before there were Nazis.)

I think we ought to re-invigorate "Philistines" as the term for "people who disagree with us even though we haven't listened to what they said". It's got a better flavor, ya'know? and the whole historical angle should appeal to the kiddies.
