sex-segregated sports are ridiculous to begin with, only created because men were afraid of losing to women. the idea that women should be segregated from sports justifies itself by assuming that women are inherently inferior to men in any given physical activity, which is literally not true and just flat out sexist. sports are not supposed to be fair, and excluding people based on their gender because you think an entire sex will perform worse sounds absurd when put into words. women's sports leagues weren't created out of fairness in the first place. they were created because women were literally not permitted by men to play with/against men professionally.
