As I said in the article, I can see the argument for loos.

Women's bathrooms have stalls, so if you see somebody who looks like a woman walk into a bathroom and go into a stall, I don't think anybody is going to have any issue. And this is clearly a more sensible solution than having a trans women who looks like a woman go into the men's bathroom. Or having trans men use the women's.

But communal changing rooms, prisons, yes, I agree that a person with a penis doesn't belong in these women's spaces.

As for sports, there aren't many more important things to worry about if you happen to be a woman who's dedicated countless hours of training and sacrifice to your chosen sport.

And think about how many women and girls have been inspired by Serena Williams, for example. Women's sport might not matter much to you, but it matters.
