World Rugby’s trans women ban is a wise idea

By the time I was 15, I had put two rugby players in hospital. I broke the arm of one and knocked the other unconscious. Both were legitimate tackles, I was just better developed: bigger, stronger and more aggressive than my opponents.

I got my comeuppance in New Zealand when, as a 19-year-old, I launched myself at a Polynesian second row in an Under-21 match.
