Climate change denier Dinesh D'Souza posted a bizarrely offensive tweet on Sunday comparing teen eco-warrior Greta Thunberg to an Aryan poster girl used by the Nazis.

The far-right filmmaker and political commentator shared a photo of Thunberg next to the Nazi poster in a tweet slamming liberal efforts to stop climate change.

'Children—notably Nordic white girls with braids and red cheeks—were often used in Nazi propaganda,' D'Souza wrote.

'An old Goebbels technique! Looks like today's progressive Left is still learning its game from an earlier Left in the 1930s.'

Thunberg made international headlines last week as she inspired millions of people across 150 countries to take to the streets for the Global Strike 4 Climate on Friday.

Prior to the strike, the 16-year-old Swede addressed Congress and criticized President Donald Trump's decision to withdraw the US from the Paris Climate Change Agreement early in his tenure.

D'Souza is one of Trump's staunchest supporters, having been pardoned by the president in May 2018 for a felony conviction of making illegal campaign contributions in 2012.

He has consistently dismissed well-established science behind global warming as a political ploy orchestrated by the left.

In his tweet, D'Souza asserted that Thunberg is being used as a political pawn to further the liberal agenda.

The Fox News contributor accused 'today's progressive Left' of a technique similar to those used by Paul Joseph Goebbels, a Nazi politician and Reich Minister of Propaganda in Germany from 1933 to 1945.

Goebbels, one of Adolf Hitler's closest associates, was known for his public speaking skills, which he used to spread his staunchly anti-Semitic views.

D'Souza's tweet was not well-received as dozens of people slammed the commentator for his unfounded assertion.

'Dinesh they should have locked you up, climate change is real and that girl is a heroine,' one person wrote.

'Dude I'm conservative but this sounds downright kookey,' another tweeted.

'Remember which side of history you're on, @DineshDSouza,' another wrote. 'Only ONE side here is pumping Nazi ideologies, and it’s not the left. Only ONE side has literal NAZIs supporting it/on it, and it’s not the left. You are so, so terrible, but this is not new news.'

One user flagged the post to Twitter, writing: 'She's 16 years old. Why even have a hateful conduct policy if you won't enforce it?'

Several people replied with photos of conservative politicians who resembled Nazi propaganda, including Vice President Mike Pence.

Thunberg made her own strong stand against climate change organically in 2018 when she skipped school to stage a one-person demonstration outside Sweden's parliament in Stockholm.

Her protest ignited a nationwide movement in Sweden thanks to social media and earned Thunberg a Nobel Prize nomination.

On Saturday the teen joined 700 other youth leaders at the United Nations' Youth Climate Summit to demand radical moves to fight climate change.

'We showed that we are united and that we, young people, are unstoppable,' Thunberg said of her 2018 protest.

The youth summit came before a full-on climate conference next week at the UN General Assembly, which has placed the issue of climate change at front and center as world leaders gather for the annual meeting.
