Here’s the thing. If Trump was a normal president, this would be exactly the correct response.
But the problem is that Trump has a such a profound case of Narcissistic Personality Disorder that people who deal with and write about the disorder almost cannot make themselves believe it’s not an act because no one ever has such a classic and extreme presentation. And that means that what she has really done is inflict a psychic wound on Trump roughly equivalent to that experienced by a normal person who has just walked in on his or her SO shagging his or her best friend. That is truly how he experiences every slight, even the mildest rebuke or contradiction.
And the result of that is that she is now his enemy. She has called him a liar, contradicted him, belittled him, personally attacked him. And he must now make it his mission (one of them, anyway), however long it takes, to avenge this wound. He won’t hesitate to take it out on the meaningless brown people either, to make them suffer the way her words made him suffer.
The fact that he is mentally ill does not make it the wrong response. It was still the right response because if she had responded with flattery, the only acceptable form of communication about him, nothing more would have been obtained. But she, and her people, are now his deadly enemy, and the more he is forced to help Puerto Rico, the greater his rage.
Tweets personally attacking her are highly likely starting at sundown today and continuing until sundown tomorrow. And if he can’t do that, it will be displaced onto someone else.
