How we identify — according to race, ethnicity, sexual orientation, religion or gender — is at the heart of hundreds of bills in legislatures across the country. And as U.S. voters across the political spectrum gear up for the 2024 presidential cycle, debates are intensifying about how to define the nation’s values around these issues.

Just weeks ago, the U.S. Supreme Court announced it will hear arguments on the constitutionality of state bans on gender-affirming care for transgender minors.

The issue has emerged as a big one in the past few years. While transgender people have gained more visibility and acceptance in many respects, half of U.S. states have instituted laws banning certain health care services for transgender kids.

In recent years, voters have been particularly fired up about the lessons and books that should, and shouldn’t, be taught to children about their bodies or the nation’s past. But those culture wars have also come to corporate America and college sports.

These renewed culture wars have take over everything from local school board meetings to state legislatures and the U.S. Capitol.
