The recent violence at Trump rallies has been the work of protesters, not of his supporters. I am no fan of Trump, but he has as much right to speak without disruption as any citizen. Indeed, it is even more important to afford him that right than ordinary citizens, because he is the presumptive nominee of one of our two major parties. Violence distracts from the debating his ideas, such as they are, and will create greater political polarization at the expense of deliberation.
Sadly, there is a connection between this violence and the enforcement of political correctness in our educational institutions today. The disruptive protesters at Trump rallies are almost all young—recent products of our educational system. They are thus steeped in the unreformed religion that dominates our schools—one where error has no rights.
Indeed, when Trump 2016 was chalked on the sidewalk of Emory University, the administration began an investigation into who wrote it. More generally, college administrators have permitted events to be cancelled because of the threat of disorder without speaking out against such cancellations.
