Billionaire Elon Musk told advertisers that have fled his social media platform X over antisemitic content to “go f*** yourself” in a fiery Wednesday interview.

His profanity-laced remarks followed a moment of contrition in a New York Times DealBook Summit interview, as he first said “I’m sorry” for a tweet that agreed with an anti-Jewish post on X on Nov. 15.

Musk has faced a torrent of criticism since he on Nov. 15 agreed with a user who falsely claimed Jewish people were stoking hatred against white people, saying the user who referenced the “Great Replacement” conspiracy theory was speaking “the actual truth.”

On Wednesday Musk said he had “handed a loaded gun” to detractors, describing his post as possibly the worst he had made during a history of messages that included many “foolish” ones.

The Tesla CEO bristled at the idea that he was antisemitic and said that advertisers who left X, formerly known as Twitter, should not think they could blackmail him, saying “f*** you” numerous times. At one point he added the words “Hey Bob,” an apparent reference to Robert Iger, chief executive of Walt Disney, which pulled ads on X.

The “Great Replacement” theory holds that Jewish people and leftists are engineering the ethnic and cultural replacement of white populations with non-white immigrants that will lead to a “white genocide.”
