Trump attacked Thunberg in a tweet earlier this month, stating it was a “so ridiculous” for Time to name her person of the year.
The president at the time tweeted: “So ridiculous. Greta must work on her Anger Management problem, then go to a good old fashioned movie with a friend! Chill Greta, Chill!”
Thunberg, who has been open about having Asperger’s syndrome, did not seem fazed by Trump’s tweet. Shortly after the Twitter attack, Thunberg changed her Twitter bio to read: “A teenager working on her anger management problem. Currently chilling and watching a good old fashioned movie with a friend.”
The teenage activist was also recently called a “brat” by Brazilian President Jair Bolsonaro, a leader who is friendly with Trump and a fellow climate skeptic. His attack came in response to Thunberg criticizing deadly attacks on indigenous Brazilians in relation to the country’s deforestation of the Amazon rainforest.
Thunberg brushed off the attacks from world leaders like Trump and Bolsonaro in the BBC interview on Monday.
“Those attacks are just funny,” she said. “It means they are terrified of young people bringing change, which they don’t want, but that is just a proof that we are actually doing something and they see us as some kind of threat.”
