J.D. Vance just the latest right-thinker to be smeared by leftist lies

If you want to understand the power of social media in weaponizing and accelerating the left’s attack on truth and ­decency, look no further than The Washington Post’s false accusation this week that J.D. Vance, author of the bestselling memoir “Hillbilly Elegy,” is a closet white supremacist.

This is the anatomy of a Twitter lynching, a good man’s reputation strung up and beaten to a pulp. In the impressionistic half-life of ­social media’s attention span, the damage can never really be undone.
