“Who’s Crazy Now?” he asks.

A conspiracy theory, says Wikipedia, “attempts to explain the cause of an event as a secret, and often deceptive, plot by a covert alliance.” Claims that global warming is a hoax and that the liberal media are suppressing the good news from Iraq meet that definition. In each case, to accept the claim you have to believe that people working for many different organizations — scientists at universities and research facilities around the world, reporters for dozens of different news organizations — are secretly coordinating their actions.

But the administration officials who told us that Saddam had an active nuclear program and insinuated that he was responsible for 9/11 weren’t part of a covert alliance; they all worked for President Bush. The claim that these officials hyped the case for war isn’t a conspiracy theory; it’s simply an assertion that people in a position of power abused that position. And that assertion only seems wildly implausible if you take it as axiomatic that Mr. Bush and those around him wouldn’t do such a thing.

The truth is that many of the people who throw around terms like “loopy conspiracy theories” are lazy bullies who, as Zachary Roth put it on CJR Daily, The Columbia Journalism Review’s Web site, want to “confer instant illegitimacy on any argument with which they disagree.” Instead of facing up to hard questions, they try to suggest that anyone who asks those questions is crazy.

Indeed, right-wing pundits have consistently questioned the sanity of Bush critics; “It looks as if Al Gore has gone off his lithium again,” said Charles Krauthammer, the Washington Post columnist, after Mr. Gore gave a perfectly sensible if hard-hitting speech. Even moderates have tended to dismiss the administration’s harsh critics as victims of irrational Bush hatred.

I think Professor Krugman has been reading Glenn Greenwald.

But now those harsh critics have been vindicated. And it turns out that many of the administration supporters can’t handle the truth. They won’t admit that they built a personality cult around a man who has proved almost pathetically unequal to the job. Nor will they admit that opponents of the Iraq war, whom they called traitors for warning that invading Iraq was a mistake, have been proved right. So they have taken refuge in the belief that a vast conspiracy of America-haters in the media is hiding the good news from the public.

Of course, as long as they’re the ones running the government, and as long as they’ve got their own media reporting from Rightie Alternate Reality Universe, they don’t have to admit the truth.

Be sure to read the whole thing. It’s brilliant.

I found the Zachary Roth post to which Professor Krugman refers. It’s from February 2004, and it’s on the use of the phrase “conspiracy theory” by a number of prominent columnists.

… the phrase serves as a dismissal, closing off debate rather than opening it up.

Loopy us. At times we could swear that some commentators are using the label “conspiracy theory” to remove uncomfortable ideas from the public debate, without having to actually come up with countervailing evidence.

Or is that a conspiracy theory?
