On Tuesday, the Supreme Court broke from its increasingly common practice of deciding important cases without holding an oral argument or even explaining the reasoning of its decision, to hear a case about whether states may ban a practice known as “conversion therapy” — therapy sessions which seek to change someone’s sexual orientation or gender identity.

About half of the states have laws banning conversion therapy for patients under the age of 18, including Colorado, whose law was before the Court on Tuesday.

Realistically, there was never any chance that this Supreme Court, which has a 6-3 Republican supermajority, would uphold the Colorado law at issue in Chiles v. Salazar. When this Court hears cases that place the interests of queer Americans against the claimed rights of religious conservatives, it consistently rules in favor of the religious right.

That said, two uncertain questions did emerge from the Chiles argument. One is whether the Supreme Court will immediately strike down Colorado’s ban on conversion therapy, or whether it will send the case back down to lower courts to apply a test known as “strict scrutiny,” which nearly all laws fail.

The more important question is to what extent the Court will strip state governments of their longstanding power to regulate health care and other professionals, at least when those professionals give dangerous advice to their patients and clients.

The Chiles case turns on two competing theories of the First Amendment.

Her lawyer, James Campbell, said at oral argument that she wants to have “full conversations exploring issues of identity and gender,” and that “includes considering chang[ing]” a patient’s identity.

He also makes a fairly intuitive argument: Talk therapists talk to their clients. Talking is protected by the First Amendment. Therefore, Colorado cannot........
