The British Association of Gender Identity Specialists have agreed with radfems about the transgender movement attracting sexual predators. They claim to have dealt with an increasing number of incarcerated sexual predators who they believe to be pretend transexuals who wish to transition to gain special privileges and access vulnerable women. They are also worried that they have lost the right to not treat individuals who they believe are not really transgender or who will pose a threat once transitioned.
