The lawsuit alleges that a CrossFit teammate of Jonnson's sent an anonymous e-mail to the games organizers asking about transgender athletes in the competition. CrossFit determined that competitors in the event had to compete in the gender of their birth....
...CrossFit maintains that Jonnson was born as a male, so she should compete in the men's division, according to a letter from the company's lawyer to Jonnson's attorney. It also stated that the company had an "obligation to protect the 'rights' of all competitors and the competition itself."
"The fundamental, ineluctable fact is that a male competitor who has a sex reassignment procedure still has a genetic makeup that confers a physical and physiological advantage over women," according to the letter from CrossFit's lawyer sent in October.
