Oh, longer than that. I witnessed it with my own eyes on the Berkeley campus thirty years ago. At first it was easy to ridicule and shrug off the “politically correct” language police with their “vertically challenged” instead of “short.” But the lunacy has since grown alarmingly out of control. These people are ignorant, superficial, self-righteous, and deadly serious. Social media have given them a weapon to deploy against anyone they deem insufficiently pure. I’ve been onto them for decades.
