Kevin Boyle reviewed two new books on the Ku Klux Klan for the Sunday Times Book Review under the heading “The Not-So-Invisible Empire.” Boyle, an Ohio State University history professor and frequent contributor to the Times Book Review, compared the Tea Party to the Ku Klux Klan. Boyle's review started and ended offensively:

Imagine a political movement created in a moment of terrible anxiety, its origins shrouded in a peculiar combination of manipulation and grass-roots mobilization, its ranks dominated by Christian conservatives and self-proclaimed patriots, its agenda driven by its members’ fervent embrace of nationalism, nativism and moral regeneration, with more than a whiff of racism wafting through it.

No, not that movement. The one from the 1920s, with the sheets and the flaming crosses and the ludicrous name meant to evoke a heroic past. The Invisible Empire of the Knights of the Ku Klux Klan, they called it. And for a few years it burned across the nation, a fearsome thing to -behold.
