Gene Simmons of KISS and Neil Young have announced they are leaving X (formerly Twitter) following Elon Musk’s endorsement of an anti-Semitic conspiracy theory.

Musk supported a post claiming Jewish communities promote “hatred against whites,” known as the “great replacement” theory.

Simmons did not specify why he was leaving but simply announced, “I’ve decided to end my X/Twitter posting.”

Young also revealed his departure on his website, stating, “We are stopping all use of X we can control,” criticizing Musk’s stance.

Young shared a message urging reconciliation and focusing on unity for the future. Musk’s comments sparked backlash, with the White House condemning the promotion of hate. Following the controversy, major companies like Disney and Warner Bros pulled ads from the platform, citing concerns over anti-Semitic content. Musk has denied being anti-Semitic, claiming his remarks were aimed at groups like the Anti-Defamation League, not all Jewish people. He also threatened legal action against media outlets reporting on the issue.
