Donald Trump’s use of post-truth double-think politics is a threat to liberal democratic norms.

The election of Donald Trump to the presidency has sparked new debates over the nature of “truth” as the new administration uses “alternative facts” to support its own narratives. Simon Kaye and Clayton Chin write that the wider implications of this new discourse about truth have been largely missed. They argue that Trump and his followers’ use of “alternative facts” is an anti-democratic refusal to engage in liberal democracy under its established norms.
