I am increasingly sure that there is a biochemical and  consequently innate reason why  trans people are trans, because if it were a choice, I do not think (m)any  trans people would choose to  be trans. We might say that  we wouldn't change things  now ... but  certainly deep down I'd much rather not  be trans, I'd much rather  be  a cisgender Nicola Jayne or a cisgender 'That Boy'...  but  that  is not  the hand i've been dealt
