If there's one thing journalists love, it's pretending that every flaw evident among conservatives is mirrored exactly among liberals.
Sure, Ann Coulter may fantasize about killing journalists, and Lou Dobbs may help spread nutty ideas about Barack Obama's birthplace, and the conservative movement may have accused Bill Clinton of being complicit in dozens of murders, but reporters will rush to assure you that there are extremists on both the Left and the Right -- and they enjoy similar positions of prominence on both sides.
Enter Slate's William Saletan, whose recent feature about the "food police" contains this whopper of a false equivalence:
To justify taxes on unhealthy food, the lifestyle regulators are stretching the evidence about obesity and addiction ... Liberals like to talk about a Republican war on science, but it turns out that they're just as willing to bend facts. In wars of piety, science has no friends.
Oh, really? Many conservatives want to stop teaching evolution in schools, to pick but one obvious example. They deny global warming, even as the polar ice caps melt away before our eyes. But liberals are just as willing to bend facts, according to Will Saletan, because ... Well, because their estimates of the budgetary impact of increased obesity may be too high.
Yeah. That's the same.
(It's telling, by the way, that Saletan doesn't feel the need to list any actual conservative falsehoods by way of comparison -- he assumes it is self-evident that both sides are "just as willing to bend facts." No need to actually compare the ways in which they do so before making that assertion.)
