In a situation that recalls the recent controversy around MMA Fighter Fallon Fox, Chloie Jönsson, a trans woman, was recently banned from competing in the women's division of Reebok's CrossFit athletic competition, a high-intensity endurance fitness challenge with a cash-prize of $250,000. She is now suing Crossfit for $2.5 million for discrimination. In the letter to her lawyer, obtained by TMZ, CrossFit contends that:
"This is simply wrong as a matter of human biology and if you can't see that, there really isn't much to talk about. Chloie was born, genetically – as a matter of fact – with an X and a Y chromosome and all of the anatomy of a male of the human race. Today, notwithstanding any hormone therapy or surgeries, Chloie still has an X and Y chromosome. Thus, you're [sic] statement is categorically, empirically, false. ... 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."
