I just watched SPOTY and there was a fantastic film about Billie Jean King and her campaign to achieve equality for women’s sport. It was so inspiring, but at the same time so depressing to think it’s a fight we might need to have all over again if the rules on transwomen’s participation in women’s sport continue to be relaxed. I would love to know BJK’s views on the current situation, given how much she did to give sportswomen a voice.
