Oh Ak, have you read nothing? Gender and sexuality are not the same thing. Children may be unaware of their sexuality until puberty but they are well aware of their gender - and well aware when something is horribly wrong. But perhaps you think transpeople are lying when they say they knew from earliest childhood that their gender identities don't match their bodies. If you allow a child to live a life which accords with their identity they will have a happy childhood. The abuse is forcing and bullying a child to conform to what others think they should be rather than what they know themselves to be.
