It is a huge concern Eats, yes. I think that people are people and I can accept difference. Gender reasignment and hormones for minors, step too far.
I was a "tomboy" (hate that term) I am now very dainty although I don't do make up, hair, heels etc. I'm also gobby, confident and assertive, I don't do emoting very well (aspie????) so what am I? well I am me. many children go through phases, thank heavens many children are allowed to explore their world in a non gender specific way. Why do we jump in and label them trying to medicalise something that may actually come to be a form of human development (environmental factors.....think fish and rivers. I remember as a kid wanting to be a boy because boys seemed to have all the toys I wanted to play with! whilst I was given dolls, thank heavens no one in the 70's thought to medicalise normal behaviour.
Adults.......well lets just say they are old enough to make up their own minds and deserve respect and support.
