> This concept of “TDS” confuses me. Trump is a terrible person and a terrible president

The only thing you need to understand "TDS" is knowing that it's the exact same accusation-in-a-mirror technique the fascists use on every other topic. By preemptively asserting that the critics are "deranged", they obscure the depth of their own reality distortion field for their cult leader. And for the casual observer who sees a bunch of drama and instinctively steers clear, the default conclusion is to think that the truth must be somewhere in the middle rather than doing the work to think about who is actually stirring up the chaos.
