Grimes can respect a capitalist, especially one she's dating.

The musician, nee Claire Boucher, defended her new boyfriend, Elon Musk, in a tweet exchange Monday night after a Twitter user told her to "please ask Elon to let his workers unionize."

Grimes, a critically acclaimed songwriter and performer known for her avant-garde flair, defended Musk: "He has never prevented them from unionizing [heart emoji x2]."

"Trust me," she continued, "I've investigated this heavily and even visited factories etc."

GRIMES AND MUSK: A romance born of a shared love of AI

The musician later deleted the tweet, saying the conversation "is way too nuanced" for Twitter. She promised to revisit the subject in a Reddit AMA ahead of a forthcoming music release and asked for people to "try to see me as a human being" and "not just an extension of another person."

Musk was accused of union busting after a 2017 blogpost from Tesla factory worker Jose Moran revealed that he and fellow workers sought to unionize with the United Auto Workers. The post included allegations of high rates of injury and low wages at the factory, located in Fremont, Calif.

The Tesla CEO acknowledged to the Guardian factory workers had been "having a hard time, working long hours, and on hard jobs," and said the company's safety record improved measurably over 2016 and 2017.

"This is not some situation where, for example, we are just greedy capitalists who decided to skimp on safety in order to have more profits and dividends and that kind of thing," he said.

The Twitter-sphere was hardly satisfied with Grimes' reply. Another user asked how Grimes could call herself "anti-imperialist" while also dating "one of the biggest and most prominent capitalists out there."

Grimes' responded she "can respect a capitalist" when they "throw the phuck down" to create cheaper public transit (Musk's Boring Company), take humans to space (SpaceX), move the world toward clean energy (Tesla) and support a universal basic income.

'Every detail tells a story': Elon Musk talks helping Grimes design her Met Gala look

People with "differing views on economics often hang out," she said, stressing whom she dates is "irrelevant to my music."

Musk and Grimes caused a stir earlier this month when the duo stepped out as a couple at the annual Met Gala in New York City.
