Reasoned debate is a foundation of our culture, Dalrymple says at Taki’s Magazine. But at the moment, neither Donald Trump nor his detractors seem much interested in it.

For what is political correctness other than an attempt to close down or preclude disinterested inquiry after truth on important selected subjects?
