you joke, but we even have empirical evidence now that

1. anti-trans policies do not decrease the rate of crime against women and girls, and similarly
2. trans-inclusive policies do not increase the crime rates against women and girls:

When laws permit transgender people to access sex-segregated spaces in accordance with their gender identities, crime rates do not increase. There is no association between trans-inclusive policies and more crime. As one of us wrote in a recent paper, this is likely because, just like cisgender folks, “transgender people use locker rooms and restrooms to change clothes and go to the bathroom,” not for sexual gratification or predatory reasons.

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.
