I feel like this is shortsighted. Instead, legislation should be in place to add another category so that there is a space for sex and gender. Not that I would expect such based actions from this dude.
I know males are on average stronger than females, but I have yet to meet a trans girl who I couldn’t beat in a physical challenge. I’m under average height, don’t work out, and I don’t have genes that give me muscular advantage, but in every physical challenge thus far, they came first.
