I feel fairly sure that I would have gone along with this without protesting, if I'd known it was happening in my sport. I discovered sport at University. I was very young, very compliant, very ambitious, very apolitical and was taught to do what the coach said. My best scores were for my 'attitude', ie obedience and willingness to hurt myself. I even read books where the message was 'do what the coach says without question'. There's a reason young people doing sport are so vulnerable to sexual abuse. If I'd been told 'this is Charlie, she transitioned, isn't it brilliant that she competes with us now, oh and BTW there are lots of horrible people who would attack her if they knew she was here, it's your job to protect her' i wouldn't have said a thing. A transwoman did compete in our headline student event in 2015 long after i was there, and not one of those women in their team or the opposing team spoke out.
I'm glad others wouldn't have been so weak but I don't blame very young women growing up now for not protesting.
