“I just want to show trans kids and younger trans athletes that they’re not alone,” she said. “They don’t have to choose between who they are and the sport they love.”
But women and girls do. They have to feel alone, bullied and ostracised if they dare to object or speak the truth. They don't even get to choose to the sport they love - there's no point them doing it at all if it's open to males which means the females are ruled out of winning.
LGBT category would be wrong because LGB has nothing to do with this issue, plenty of sportspeople are gay or bi and already in the correct categories. I would go for an "open" category. Male, female, and open. Everyone can choose the category for their sex, or if they don't feel they belong there because of "gender", they can choose the open category. In that category, a male can announce themselves as a woman and wear a women's cossie if they want to, because it would make no difference as it's fully open. Meanwhile females get a female-only category.
