Both times Trump has tweeted about her, Thunberg’s responses have been jocular, and sarcastic in kind. This week, she changed her Twitter bio to: “A teenager working on her anger management problem. Currently chilling and watching a good old fashioned movie with a friend.”

In her handling of being cyberbullied by the president of the United States, at age 16, Thunberg has become an inspiration for girls two times over – first as a climate activist, then as a social media ninja.

But that doesn’t mean that Trump’s cyberbullying of Thunberg is any less despicable, or dangerous. What it says to girls all over the world is: no matter what you do, no matter how much you achieve, powerful men can and will try to cut you down.

This message is depressing, scary and not without potentially dire consequences. It’s a message that has contributed to a precipitous rise in the suicide rate among girls.
