Firstly I've always wondered if separate categories perpetuate the idea that female athletes are somehow inferior @LolaandTim
Look, its not ' equality' to deny difference. Pretending we are all the same in every way is not progressive, its just a bit thick. Its pretty much like those people who try to proclaim their anti-racism by declaring proudly, ' I don't see colour!'
The best women are not as good as the best men at sports, not cos the women are just a bit crap or not trying hard enough but simply because our bodies are different. For so many areas of life, not just sport, its important, for women's safety, dignity and fairness, that we recognise this.
