The right-wing rhetoric around “P.C.” has always made use of martial metaphors — the “P.C. police,” the “feminazis” that Limbaugh popularized and their modern equivalent, “social justice warriors” — with a sly wink. These were, after all, sissy liberals engaged in stultifying cultural squabbles. But now Trump has deepened the insinuation, framing political correctness as a kind of fifth-column tendency, an actual danger to America. In his campaign, “P.C.” is no longer just a joke, or a slick rhetorical tool for riling the base. It’s the shrewd recognition of a dark aspect of white American psychology: That many experience being told not to use certain words as a kind of violence. For people who live free of the threat of police brutality and racist aggression, simply being called racist is a wounding personal attack. As one Trump supporter complained to BuzzFeed, “every other ethnicity” gets “a free card to say whatever they want and be completely accepted. But whenever I and many other people that might be sympathetic to the larger group of people say something, automatically it’s racist. It’s hypocritical and it’s wrong.”
