As the adage goes, “Accuse your opponents of that which you are guilty.” Avoid the blame, or embarrassment, for your own vices by first declaring that your enemies are guilty of those same ills so that the disgust and attention are shifted away from you.
The American Left has all but mastered this tactic, having successfully accused the Republican Party—and the Right as a whole—of being bigoted, sexist, racist, and the like, while completely erasing the Democratic Party’s history as supporters of slavery, against women’s suffrage, and in favor of segregation and Jim Crow. Their dramatic switch came only when it was politically expedient for them to attempt it, as Lyndon Johnson understood with his infamous (private) declaration before signing the Civil Rights Act of 1964. (For those who aren’t aware . . . let’s just say Johnson had a blunt way of declaring that African-Americans would be loyal to Democrats for the next two centuries.)
But this tactic has never before been used so liberally (pardon the pun) as it is used today, where just about every person to the right of Joseph Stalin is “literally Hitler,” anyone who voted for Trump (if even reluctantly) is “alt-right,” and anyone who opposes open borders, multiculturalism, and globalism is “far-right.” Everyone from libertarians to Christians is part of some kind of fringe, although the definition of “fringe” now encompasses the bulk of the cloth.
