Conversely, when trans people are forced by law to use sex-segregated spaces that align with the sex assigned to them at birth instead of their gender identity, two important facts should be noted.
First, no studies show that violent crime rates against cisgender women and girls in such spaces decrease. In other words, cisgender women and girls are no safer than they would be in the absence of anti-trans laws. Certainly, the possibility exists that a cisgender man might pose as a woman to go into certain spaces under false pretenses. But that same possibility remains regardless of whether transgender people are lawfully permitted in those spaces.
Second, trans people are significantly more likely to be victimized in sex-segregated spaces than are cisgender people. For instance, while incarcerated in facilities designated for men, trans women are nine to 13 times as likely to be sexually assaulted as the men with whom they are boarded.
