NEW: Following the Supreme Court OK'ing states' trans sports bans, ADF is now taking its targeting of states with pro-trans sports policies to SCOTUS — via the shadow docket in a case out of Washington. www.documentcloud.org/documents/28...

Anti cross dressing ordinances over time in the US. What's remarkable is how much of this nucleated around St Louis and the Mississippi River in the mid 19th century. There's a story there to find.

Many of the laws upheld today, like the one in Idaho, have specific provisions authorizing physical inspection. The original challenge included a cis plaintiff who feared intrusion based on her gender presentation.

The ban is heinous for what it does to transgender athletes. But if you think cisgender girls and young women won’t be caught up in the fallout, too, you are woefully ignorant

Why is it bad to define sex in the Constitution? Because the government can't dictate what your personhood means. Legislation told women for centuries that their bodies make them naturally feminine, domestic, heterosexual, and reproductive.

Kate Redburn @kredburn.bsky.social · 30/06/2026
What does that mean? The Court doesn't define it. According to Thomas's concurrence, though, it means that sex assigned at birth cannot change, and it is binary. Adopting that definition renders blatant anti-transgender discrimination invisible to the 14th Amendment.

The effect is to say that blatant discrimination against transgender people, like blanket sports bans that replaced case-by-case assessment, and blanket medical bans for minors, can pass constitutional muster.

Kate Redburn @kredburn.bsky.social · 30/06/2026
The opinion takes the 'medical context' exception to Equal Protection from Skrmetti - invented out of whole cloth to justify discrimination - and essentially applies it to the sports context with little explanation and almost no citations to purportedly empirical evidence.

Today the Court denied transgender women and girls constitutional equality. I predicted that the athlete cases could take this turn after last year's decision in Skrmetti: harvardlawreview.org/wp-content/u...

2/ But in B.P.J., the phrase "exceedingly persuasive" is absent from majority opinion, and as Sotomayor notes in dissent, the majority cites free speech int. scrutiny cases (and rational basis cases) in its application of equal protection intermediate scrutiny.

1/ One important doctrinal takeaway from B.P.J. decision is narrowing of gap b/n equal-protection intermediate scrutiny and free-speech int. scrutiny. Former had been viewed as rigorous (captured by "exceedingly persuasive" phrase), while latter long viewed (in Ct's words) as "relatively lenient."

Over the last decade, across a range of issues—from gun rights to elections to school prayer to the structure of the administrative state—the Supreme Court has decided cases on the basis of past practice.

So it seems ok to use vast overgeneralizations to keep trans kids out of sports, but strikes most people as problematic to give boys harder math problems at school. Historical discrimination was very very often justified in these terms. And rejected on those terms. Not anymore?

Kate Redburn @kredburn.bsky.social · 13/01/2026
In this back-and-forth, the government refused to take its argument to its logical conclusion: that legal distinctions justified by "real" biological differences - with the studies purporting to prove it - are often a smoke screen for blatant sex discrimination.

As the press makes sense of the arguments in the transgender athlete cases today, you're likely to see one exchange between Justice Gorsuch and Deputy SG Mooppan (like this one from NPR) www.npr.org/2026/01/13/n.... Why?

To date, 27 states have enacted laws barring transgender participation in sports.

third, the legal stakes of these cases are broader than the harms to transgender people. If these laws are allowed to stand, the Court invites legislatures to pass discriminatory laws and justify them as rooted in biological rather than stereotypes about the inferiority of women and trans people

second, the belief underlying the anti-trans athlete legislation is that girls are terrible at sports, period. The idea is that ANY person assigned male at birth will ALWAYS defeat ANY person assigned female. Obviously untrue and deeply sexist! Talk about overinclusive...

first, these athletes do not want to prevent sports leagues from engaging in any regulation whatsoever, they simply think that a categorical ban on all trans girls and women participating in women's sports is radically overinclusive. No one is challenging sex-segregated sports.
