Sufficient, but far from exclusive …
as a reason categorically to refuse one’s vote to Trump next year:
Despite right-wing persecution fantasies about Barack Obama, we’ve never before had a president who treats half the country like enemies, subjecting them to an unending barrage of dehumanization and hostile propaganda. Opponents in a liberal political system share at least some overlapping language. They have some shared values to orient debates. With those things gone, words lose their meaning and political exchange becomes impossible and irrelevant.
And don’t give me a couple of one-offs like “deplorables” or “cling to their guns and their religion.”
