Nicholas Kristof, at The New York Times:
There are crackpots who believe that the earth is flat, and they don’t deserve to be quoted without explaining that this is an, er, outlying view, and the same goes for a crackpot who has argued that climate change is a Chinese-made hoax, who has called for barring Muslims and who has said that he will build a border wall and that Mexico will pay for it.
We owe it to our readers to signal when we’re writing about a crackpot. Even if he’s a presidential candidate. No, especially when he’s a presidential candidate.
