It could be that the debate over whether it’s acceptable to call Trump mentally unfit to be president is at the heart of the weird debate over who is more weird, the Democrats or the Republicans. America is becoming unrecognisable, so fast, in so many ways, to so many different types of people, that the words “weird” and “sick” are being anxiously domesticated into neutral terms of description. Yet, in the end, the unclarity is all the more reason to be vigilant about truly aberrant figures slipping into leadership of the country under the cover of a revolution of norms. Trump is truly aberrant. Everyone knows it, his supporters as much as his detractors. No one talks like this man. No one abuses other people like this man. No one misrepresents reality like this man. And he is not lying. He is describing what he perceives, which is not what is actually there.
