Already happening in Canada, the UK and Ireland. Here's a particularly delightful gentleman: "Barbie Kardashian".

Which links to an article about "Karen White":

In 2018, Karen White, a recently self-identified trans woman [sic because he's a man, not any kind of woman] and convicted paedophile who was on remand for multiple rapes and grievous bodily harm, was sent to New Hall women's prison in Yorkshire, UK, despite not being legally recognised as female. She [sic] sexually assaulted two fellow inmates before she [sic] was transferred out to a men's prison.
