Treating trans kids as members of their gender

What are the U.S. legal arguments for treating trans kids as members of their gender (i.e., the gender in which they live and with which they identify)?

A useful resource

Please see this four-paragraph quote:

"While this [Bostock v. Clayton County (2020)] was a historic victory for transgender rights, it also left unresolved one of the most important questions that arises in such cases: whether the concept of 'gender' exists separately, as a legal matter, from 'status as either male or female [as] determined by reproductive biology.' Indeed, Bostock was decided 'on the assumption that' the term 'sex' refers exclusively to 'biological distinctions between male and female.'

And yet, even if you assume that the law refers only to 'biological' sex, Bostock still concluded that most forms of discrimination against trans people violate that law because they necessarily require treating men (or people assigned male at birth) differently than women (or people assigned female at birth).

Cases like A.C. and B.P.J., in other words, raise a question that was not resolved in Bostock. Bostock was agnostic on whether a trans man is a man. In order to decide the A.C. case, by contrast, the Seventh Circuit had to resolve 'who counts as a ‘boy’ for the boys’ rooms, and who counts as a ‘girl’ for the girls’ rooms.'

If you want a deeper dive into the legal arguments for and against requiring schools to treat trans girls just like any other girl (or trans boys just like any other boy), I wrote that deeper dive here. For now, I will simply add that the Supreme Court appears determined not to resolve this question, even though lower courts are divided on how it should be answered."

In Georgia, "Republican Sen. Carden Summers, the primary sponsor of the state’s bathroom ban bill," stopped by a mother who said she was there to "talk to legislators about keeping her kids safe." Senator Summers knelt by her daughter, an 8-year-old trans girl and said: "Well you know, we’re working on that and I’m going to protect kids like you.” The mother replied, "Yeah," adding that her daughter "is trans, and she wants to be safe at school, she wants to go to the bathroom and be safe." Senator Summers stood up, according to witnesses, saying: "I mean, yeah, I'm going to make sure she's safe by going to the right bathroom." And: "When asked if he would make her go to a boy's bathroom, he then allegedly backed away, saying, 'You're attacking me,' turned around, and walked off quickly." Erin Reed observes: "The exchange was a unique encapsulation of why anti-trans bills that ban transgender people from public spaces that match their gender identity have proven ineffectual in the past. In numerous hearings over bathroom bans, transgender people often point out that cisgender individuals cannot always tell who is and is not trans." When bathroom restrictions are enforced, they "will inevitably catch cisgender people who are gender nonconforming in the same net. Worse, it would force transgender kids into the wrong bathroom — kids who even the senator who wrote the bill innately realized he needed to protect from bathroom harassment before learning the child was trans." — Erin Reed, Feb 16, 2024

Look at this

"Most GOP-controlled states now have laws reining in their rights. Measures include laws to keep transgender girls out of girls school sports, limiting which school bathrooms transgender people can use, requiring school staff to notify parents if their student identifies in school as transgender, and barring school staff from being required to use the pronouns a transgender student uses."

It looks like a list of things that trans people aren't allowed to do.

But if you think about it, this is a big part of what it means to have a gender. If you don't have this, the foundation of gender crumbles. And the way these laws are designed, they don't aim to dismantle gender for everyone. They aim to reinforce the gender binary and keep everyone in a gender box based on whatever sex they were born as. This makes it illegal to go through a gender transition or otherwise to be trans while in school.
