 One of the cases the Supreme Court agreed to hear next term is a challenge to a law banning gender-affirming treatments for transgender minors.

Just a few years ago, not a single state had a law banning gender-affirming care. Lindsay Dawson of the health research organization KFF says it seems like the policies spread like wildfire.
