The Biden administration announced Oct. 27 that it had issued the first-ever U.S. passport with an “X” gender marker for an American citizen who identifies as intersex. The recipient, Dana Zzyym from Fort Collins, Colorado, is a 63-year-old Navy veteran and the associate director for the Intersex Campaign for Equality.

“We look forward to offering this option to all routine passport applicants once we complete the required system and form updates in early 2022,” Ned Price, a spokesman for the Department of State, said in a press release.

The department now allows applicants to select from three genders—“M” for male, “F” for female or “X” for those who identify as “nonbinary, intersex or gender-nonconforming.” Individuals are no longer required to provide medical certification if their gender does not match that listed on their other identification documents.

While the administration claims the move was purely for the sake of “promoting the freedom, dignity and equality of all people—including LGBTQI+ persons,” others are questioning the very real national security risks a genderless passport presents.

“Pretending is perfectly fine if you’re a kid playing make-believe, but this is the age of terrorism—and a passport is the most dependable form of identification our country offers,” Tony Perkins, president of Family Research Council, argued. “How can the people working to keep us safe do their jobs when a suspect could be described as either a man or a woman—or neither—depending on how they feel? … It’s impossible to protect Americans when we let people hide their true identities.”

In a Facebook post, Franklin Graham further pointed out the unscientific and unbiblical nature of a gender “X” passport:

“This is not truth or science,” he said. “We only have two genders: male and female. Gender X is not only nonsense, it is going against God who ‘created man in His own image … male and female He created them’ (Gen. 1:27, NKJV). The State Department is turning the American passport into a farce, not to mention flaunting God. Pray that those running our government will come to their senses or be voted out of office.”
