These people, who call themselves "Trans", deserve all our respect, but they are mentally ill, usually suffering from schizophrenia and paranoia. They should therefore receive psychiatric treatment.
However, I am totally against discriminating against these people, as well as against compulsory treatment. If some of these people don't want to be treated, we should respect their right to do so. But on the other hand, we also have no obligation to nurture or foster their mental illness... A man will always be a man, and a woman will always be a woman, so gender reassignment is impossible.
Whether these people like it or not, we will always treat them according to who they really are, and not how their mental illness makes them want us to treat them...
