Any “women’s” sport in which men (XY chromosomes and started life with their male anatomy intact) compete against women (real women - born that way and XX chromosomes) is a freak show and not a true sport. I will not be watching.
The heavy favorite to win the Women’s 800m was (likely) born with XY chromosomes and internal testes.

This, of course, would not be the first time this happened because. Stella “The Fella” Walsh won gold in 1932 for the USA. Granted, chromosome tests for athletes did not exist back then.
