There has been controversy about Imane Khelif taking part in women's boxing. This video explains what has happened.
Basically, she failed a gender test after beating a Russian, the test was requested by an organisation that many consider to be run by a Russian, and after she was disqualified, the Russian was officially unbeaten.
While Lin Yu-ting did not have the same issue, it may have been that her crime was that she represented Taiwan.
Sadly, it appears that these two women are casualties in the increasingly polarised binary stance on gender and gender identity, as well as being the victims of fake news, deliberately spread by what many consider to be a corrupt organisation.
As with all my posts, I am genuinely interested in what views are held on this matter and feel free to let me know what you think.
