Spanish golfer Gonzalo Fernández-Castaño has brutally compared 2019 TIME Person of the Year Greta Thunberg to Adolf Hitler in a bizarre series of tweets on Friday.
Thunberg is a world-renowned environmental activist, who has campaigned for greater action to combat climate change. The Swede made headlines in August by sailing to New York City for climate conferences, choosing not to fly in hopes of reducing her carbon footprint.
After Thunberg was announced TIME's Person of the Year on Thursday, becoming the youngest person in history to do so, Fernández-Castaño posted a map on Twitter detailing his flight paths from 2019.
"Another year in the books! Enjoy @GretaThunberg," Fernández-Castaño posted.
