The International Cricket Council has become the latest sports body to ban transgender players from the elite women’s game if they have gone through male puberty.
The ICC said it had taken the decision, following an extensive scientific review and nine-month consultation, to “protect the integrity of the international women’s game and the safety of players”.
It joins rugby union, swimming, cycling, athletics and rugby league, who have all gone down a similar path in recent years after citing concerns over fairness or safety.
Of course genetic mutations are a pretty common thing, but some are minor (like your red hair example), some are “WTF? How did that happen?” mutations, and some are straight up deadly like the various forms of cancer.
Women being XX is a classification (?) we’ve all agreed on because like 99.8% of people with XX chromosomes are women. Mutations are literally something out of the ordinary that shouldn’t happen.* A woman shouldn’t have XY chromosomes because almost every woman in history that we know of has XX chromosomes*.
