Two things, Mr. President.

First, while I, too, have questions about whether Greta Thunberg deserves her celebrity, much less being TIME's Person of the Year,
Greta has what used to be called Asperger's Syndrome. So yeah. She has anger management problems.

And your boorish insensitivity is a stain on our nation. This is not the first time you've mocked somebody for having a disability, and it's getting old.

Secondly, you are telling somebody else that they have anger management issues? You, who can't restrain himself from tweeting a schoolyard insult about literally anyone whom you hear has criticized you, or even disagreed with you- and not only doesn't wait to make sure that you have your facts straight but habitually double down on your mistake when you turn out to have been misinformed? Greta Thunberg is a teenager with high-functioning autism. But next to you she not only has world-class people skills but is the quintessence of maturity.

Before you advise Greta to "chill" or "go to a movie with a friend-" before you dare to comment about somebody else's personality quirks- you need to reach the level of personal maturity of a teenager with high-functioning autism yourself.

Sir, it has been obvious your entire "adult" life that, due respect for your office aside, there is something about your psyche that is neither healthy or wholesome, and it doesn't take a mental health professional to see that. You convince those of us who are not your partisans of that every single day.
