There are a lot of angry nuts on my side of the aisle [the right]. They simply can’t believe that Barack Obama somehow got elected president and they feel powerless right now.
But here’s the thing: There’s plenty of crazy to go around. Remember Bush Derangement Syndrome? The 9/11 conspiracy theorists who thought Bush and Cheney were in on the whole thing? The Diebold plot to steal the 2004 election? Should we judge the Left by the whackos that show up at the anti-trade rallies? PETA? Greenpeace? Of course not. Almost by definition, the people motivated and available enough to show up in the middle of the day to express their outrage about something are not like you and me.
"Bush Derangement Syndrome" was shorthand (invented by Charles Krauthammer, of all people) for the (fallacious) ad hominem tactic Bush supporters used to malign critics of all things Bush. So, saying, "Remember Bush Derangement Syndrome" as evidence of the wrongness of your opponent is like saying, "Don't you remember how I used to lie about you, didn't that show you were wrong?"
