I just wanted to say. When you have a baby the weight charts for boys and girls are on different pages. Right from the beginning there are physical differences between boys are girls.
Where sport is segregated it needs to be done based on sex. What possible sense can it make to segregate sports based on gender identity?
Actually this makes me question the whole premise of being trans gender. I did think that it was ok to support people's belief/wish to be a man/woman but I think it causes too much damage along the way to collude in these delusions.
