Green Party vice-presidential nominee Butch Ware came out against allowing biological men to compete in women’s sports in a video circulating on social media.

The Green Party is known to frequently run to the left of the Democratic Party on several issues, often championing social justice and diversity causes like gender identity. Ware called allowing biological men to compete with women “unfair” in a video posted on X, a position that appears strikingly out of step with the party’s platform.

“I don’t think that biological males should play in female sports,” Ware said. “It gives an unfair competitive advantage.”

The issue of biological males who identify as transgender competing in women’s sports became a hotly debated topic following Lia Thomas’s participation in the 2022 NCAA championships, where the biological male won the 500-yard women’s final.

Multiple college teams elected to forfeit matches against San Jose State University’s women’s volleyball team due to the presence of a biological male on the San Jose State roster, according to the Los Angeles Times. The transgender player also spiked a ball into the face of a San Diego State University female player during an Oct. 10 match, the New York Post reported.

North Carolina high school volleyball player Payton McNabb suffered a career-ending concussion when a transgender player’s spike hit her in the face in a similar play during a September 2022 volleyball match. McNabb described ongoing medical symptoms in legislative testimony given in April 2023.

Former President Donald Trump’s campaign has run ads featuring Vice President Kamala Harris discussing how she pushed “behind the scenes” for transgender prisoners to receive sex changes, while Trump said he supported banning biological men from competing in women’s sports during an Oct. 16 town hall moderated by Fox News host Harris Faulkner.

Harris and Trump are deadlocked at 47.1% in surveys where Green Party candidate Dr. Jill Stein, independent candidate Cornel West and Libertarian candidate Chase Oliver are included, with Stein pulling 1.1% of the vote. Harris trails Trump in five battleground states, according to the RealClearPolling average, and her leads in Wisconsin and Michigan are smaller than Stein’s support.
