On March 30, the states of Oklahoma and Arizona joined the growing list of states which prohibit transgender women and girls from playing in female sports divisions. Both laws are rooted in the claim that trans athletes have an unfair advantage due to higher levels of testosterone before transition, and that this makes sporting competitions unfair. The vast majority of the individuals leading this charge against trans sport participation have no past history of caring about women’s sports or women’s rights in general. These are not unrelated, but part of a reaction to the last few decades of progress on LGBTQ+ rights and women’s rights.
