I also get a bit exasperated at these implications that trans women transition in order to get closer to their 'prey'
However, inconveniently for you, this happens to be true:
"Testimony admitted by the British Association of Gender Identity Specialists to the Transgender Equality Inquiry in the UK Parliament took a surprise turn when members sounded the alarm over what they warned is an “ever increasing tide” of transwoman criminal sex offenders. They outline how sex-offending transwomen whom they describe as “pretend transsexuals” adopt a transgender identity for various nefarious purposes, often involving increased access to vulnerable women and child victims.
Description of the British Association of Gender Identity Specialists, from the August 20, 2015 testimony to Parliament [PDF] [all bolding in this post by me-GM]:
The Association numbers over a hundred members and comprises the overwhelming majority of all clinicians working in every Gender Identity Clinic in the British Isles. The membership is drawn from all the involved disciplines and includes Speech Therapists, Psychologists, Psychiatrists, Surgeons, Psychosexual Counsellors, Nurses, Occupational Therapists, Endocrinologists, General Practitioners and Social Workers.
Their testimony:
"The converse is the ever-increasing tide of referrals of patients in prison serving long or indeterminate sentences for serious sexual offences. These vastly outnumber the number of prisoners incarcerated for more ordinary, non-sexual, offences. It has been rather naïvely suggested that nobody would seek to pretend transsexual status in prison if this were not actually the case. There are, to those of us who actually interview the prisoners, in fact very many reasons why people might pretend this. These vary from the opportunity to have trips out of prison through to a desire for a transfer to the female estate (to the same prison as a co-defendant) through to the idea that a parole board will perceive somebody who is female as being less dangerous through to a [false] belief that hormone treatment will actually render one less dangerous through to wanting a special or protected status within the prison system and even (in one very well evidenced case that a highly concerned Prison Governor brought particularly to my attention) a plethora of prison intelligence information suggesting that the driving force was a desire to make subsequent sexual offending very much easier, females being generally perceived as low risk in this regard. I am sure that the Governor concerned would be happy to talk about this."
