A Classic example of
"Damning with Faint Praise"
From the BBC on the suggestions going around in America about Trump's Mental health
"
Dr Allen Frances, who helped write the Diagnostic and Statistical Manual of Mental Disorders IV, one of the main key manuals used to classify mental disorders, said that "most amateur diagnosticians have mislabelled" Mr Trump with the diagnosis of "narcissistic personality disorder".
"He may be a world-class narcissist, but this doesn't make him mentally ill, because he does not suffer from the distress and impairment required to diagnose mental disorder."
He added: "Mr Trump causes severe distress rather than experiencing it and has been richly rewarded, rather than punished, for his grandiosity, self-absorption and lack of empathy.
"It is a stigmatising insult to the mentally ill (who are mostly well behaved and well meaning) to be lumped with Mr Trump (who is neither).
"Bad behaviour is rarely a sign of mental illness, and the mentally ill behave badly only rarely. Psychiatric name-calling is a misguided way of countering Mr Trump's attack on democracy."
I'll bet Trump didn't like that
(Assuming someone explained to him what it meant of course.)
More likely they didn't tell him anything to "set him off!"
