The PC left and the alt-right exist symbiotically with one another: Working together to exacerbate tribal loyalties, to undermine the legitimacy of the state as a political unit, to question the idea that Western institutions can really treat groups of people with equal respect—in other words, to draw out and hijack the inherent weaknesses and contradictions in the Enlightenment liberal tradition. It’s unlikely that either movement has the cultural power or breadth of appeal to succeed on its own. But taken together, they make a fearsome foe.
