Lance Berkman, a former star on the Houston Astros, has come out against a Houston local ordinance that calls for the equal protection of LGBT people. He brings up the theory that if men were allowed in women’s restrooms, it would put women “in harm’s way.”

The ad is sponsored by the Campaign For Houston, which wants residents to vote against the Houston Equal Rights Ordinance. As USA Today notes, it will appear on the Nov. 3 ballot as Proposition 1.

“I played professional baseball for 15 years, but my family is more important,” Berkman says in the ad, which was posted at Out Sports. “My wife and I have four daughters. Proposition 1 would allow troubled men who claim to be women to enter women’s bathrooms, showers and locker rooms. It’s better to prevent this danger by closing women’s restrooms to men rather than waiting for a crime to happen. Join me to stop the violation of privacy and discrimination against women.”

The ad uses the popular imagery those against this ordinance and similar ones use to gain support. They believe that allowing a transgender man - referred to as a “troubled man” by Berkman - into a woman’s restroom would put women and girls in danger.

According to the Human Rights Campaign, the Houston ordinance aims to protect employees from discrimination based on race, sexual orientation, gender, religion, disability, pregnancy and other traits. The HRC says that Houston is the largest city in the country without a similar ordinance.

Berkman is a Texas native and played for the Astros from 1999 to 2009. He retired in 2013.
