on the aforementioned definition of their sex. Unisex public toilets are one option to overcome this controversy. Critics of bills which exclude transgender individuals from restrooms which conform to their gender identity argue that they do not make public restrooms any safer for cisgender (non-transgender) people, and that they make public restrooms less safe for both transgender people and gender non-conforming cisgender people. Additionally, critics claim there have been no cases of a transgender person attacking a cisgender person in a public restroom, although there has been at least one isolated incident of voyeurism in a fitting room. By comparison, a much larger percentage of transgender people have been verbally, physically, and sexually harassed or attacked by cisgender people in public facilities. For these reasons the controversy over transgender bathroom access has been labeled a moral panic. Proponents say such legislation is necessary to maintain privacy, protect what they claim to be an innate sense of modesty held by most cisgender people, prevent voyeurism, assault, molestation, and rape, and retain psychological comfort. One bathroom bill, the Public Facilities Privacy & Security Act in North Carolina, was approved as a law in 2016, although portions of the measure were later repealed in 2017 as part of a compromise between the Democratic governor and Republican-controlled Legislature.

Trans athletes in sports Nineteen U.S. States have banned transgender people from participating in sports in their gender identity. These states include Texas, Arkansas, Florida, Alabama, Oklahoma, Kentucky, Mississippi, Tennessee, West Virginia, South Carolina, Utah, South Dakota, Montana, Iowa, Arizona, Idaho, Indiana, Louisiana, and Georgia. The passage of legislation against transgender youth has seen increases in calls to Trans Lifeline, a suicide crisis hotline run by and for transgender people. The Human Rights Campaign has argued that these discriminatory laws are not about protecting women’s sports, but rather are attempts to “undermine the existence of transgender people. Transgender advocates have noted that hormone replacement therapy and testosterone suppression reduces muscle mass and physical strength in transgender women, reducing the possibility of a competitive advantage. Transgender inclusion in sports is supported by the Women’s Sports Foundation, the Women's National Basketball Players Association (WNBPA), the National Women's Law Center, and Athlete Ally, as well as United States Women's National Soccer Team Captain Megan Rapinoe, tennis legend Billie Jean King, WNBA
