A person born male does not become a female by choice. He may be attracted to the same sex or both sexes, but he is still male. He may prefer to wear clothes that are typically worn by females, but he is still male. He may walk or have a manner of holding their arms, hands, stand etc, that people typically characterize as feminine, but he is still male. People claiming otherwise are harming people who genuinely have gender dysphoria - which is extremely rare. What should change is the lack of accepting that a male can have all these desires, attractions, mannerisms etc. and still be acknowledge as a male who is normal and OK. The other things are society imposed norms. His gender is imposed by his chromosomes. This nonsense has got to stop.
