Only other liberals will be shamed into silence by terror of being labeled a racist (a slur generously lobbed at me in recent days, and one that, however unfounded, tends to stick). But there’s still such a thing as a real bigot and a real misogynist. In obsessing over “microaggressions,” like the sin of uttering the commonplace Americanism “you guys” to mean “you all,” activists persecute the very folks who already care about decency and equal rights, while providing fodder for proper retrogrades, who can dismiss concerns about still-pervasive discrimination as so much twaddle.
