XY Will Always Be XY

The boxing gender argument continues but for me it is straight forward, last year both Algeria’s Imane Khelif and Taiwan’s Lin Yu-ting were disqualified from the World Championships as both fighters failed gender eligibility tests while participating in the women's competition and were found to have competitive advantages over other female competitors.
The  International Boxing Association (IBA) chief executive Chris Roberts said male XY chromosomes were found 'in both cases' after 'ongoing concerns raised by other fighters, coaches and the IBA’s medical committee'.
The International Olympic Committee (IOC) cast doubt on the reliability of the tests which is why both are now fighting in the Women's Boxing matches at the Olympics resulting in one challenger quitting after 46 seconds due to being hit so hard that she felt: 'I had to preserve my life as well in that moment'.
I don't know if the IOC have conducted their own gender tests, it was be amazing if they haven't after all the controversy but especially in such a dangerous Sport as Boxing, anyone who has a competitive advantage should not be allowed to compete.
I know this puts me very much on the opposite side of some people who feel this is unfair to anyone who's gender is different to the one they were born with but as i never tire of pointing out, you can choose your gender but you can not choose your sex, and no operation or hormone drugs will change the biological facts that a person is XY or XX and that should always be the deciding factor.
