In a shocking (but not entirely surprising) move, Elon Musk has spoken out about the issue of transgender athletes in sports. The tech billionaire, who is known for his cryptic tweets and controversial opinions, has called for a boycott of male athletes competing in women’s competitions.

“This is a blatant injustice!” Musk tweeted. “We need to protect the integrity of women’s sports!”

Of course, Musk didn’t stop there. He also proposed “massive” penalties for anyone caught cheating. “We’re talking about stripping medals, lifetime bans, and possibly deportation from Mars,” Musk warned.

The reaction on social media was mixed. Some praised Musk for “standing up for the truth,” while others criticized him for making “insensitive” and “divisive” comments.

“Elon Musk should focus on building electric cars and rockets instead of meddling in issues he doesn’t understand,” one Twitter user wrote.It’s unclear at this point whether Musk’s call for a boycott will be followed. But one thing is certain: it has sparked a heated debate on the issue.

And in a related development, Musk also announced that he is developing a new test that can detect whether an athlete is transgender. “It’s called ‘The Truth Serum,’” Musk tweeted. “And it’s available tomorrow.”

“I agree with Elon Musk,” another wrote. “It’s not fair for male athletes to compete against women.”
