Othering, at its most extreme, is a step towards accepting a kind of loose solipsism, a step towards making you believe that everyone else is somehow not really as human as you. That is a path to enabling, if not at worst endorsing, fascism. And make no mistake—Trump’s comments both enable and endorse fascism. “Political correctness” cannot be a cover for ignorant prejudice.

Fear is the mind-killer, as the Bene Gesserit recite in the Dune series. So, too, is hatred.
