If only we had a decent search facility! It has been said time and again on threads on this subject that a transwoman in a rape suite would be an issue, but the concerns were poo-pooed as an unreasonable, with the usual 'who will police it?' and 'I am not going to look under people's clothes!' retorts.
My view has always been that nobody has an inalienable right to follow a particular career. If they did, there would be no entry qualifications, and no interviews as they would be seen as discrimination based on intelligence/subject knowledge and perceived suitability for coping with the demands of the role. If someone is afraid of violence, it is not a good idea for them to join the police, and so on.
Most people grasp this at a young age, and find a career that is suitable for their temperament and abilities. There may be many frustrated astronauts and ballerinas around, but on the whole we adjust to our disappointments and get on with it.
If someone is transexual and realises this after starting a career in medicine, would it not make sense to diversify into one of the numerous areas of expertise that is not gynaecology or obstetrics? Or go into research, or teaching, if it is too late to change path? Similarly, if someone is an excellent counsellor when they transition, why not go into a less contentious area than rape counselling?
Doing this would not be life or career limiting in either case, but it would respect the fact that there are times when women don't want men around them - even men who have transitioned to transwomen. That doesn't make those women bigots - many women who have been raped don't want to be intimate with their husbands or partners for a while afterwards - it makes them traumatised and in need of non-judgemental consideration and care.
A genuinely concerned counsellor of whatever gender would know this, as, IMO, would any decent human being - particularly one who will have been on a difficult road to find acceptance as a transperson.
