Not intended to be patronising and I can only really speak about my father's experiences and the limited number of other transexuals that I met through him. Like I have said nothing that a family member or friend can say will have any effect on how a transexual chooses to behave with regard to their condition.
The point that some seem to be missing is that transexual women, born a women but wishing to change into a man through hormone treatment and surgery, I assume, currently may use male only spaces such as male toilets. Any change in the law, depending on how it was drafted and worded, that effectively banned transexual men (born a man) from accessing female only spaces may also have the effect of banning transexual women (born a woman but wanting to be a man) from using male only spaces and thus force them into using female only spaces, such as female toilets. One could, possibly, end up in a situation, dependant on how any change in the law is worded, with transexuals who look very convincingly like men, but born a woman, being forced to use female toilets and transexuals who look like women, but born a man, being forced to use male toilets.
In answer to a previous question one of the "treatments" offered/available to transexuals in times past was, I believe, electric shock "treatment" to the brain. My understanding is that this "treatment", at one time was given for a wide variety of conditions and involved an "electrode/s" placed on one's head with varying degrees of electrical current/voltage being passed through one's brain. I don't believe that there is any evidence of any sort of benefit of using this device but my understanding is that it was extremely painful for anyone undergoing this form of "treatment".
