Disagreement over sex and gender have cleaved the feminist community between those who believe that biological sex is immutable, and those who believe that transitioning sex to align body with brain is not only possible, but a legally binding marker of identity. Courts, social-services organizations and schools all have been pushed to adopt the most doctrinaire precepts of trans-rights advocacy. In some cases, the issue has divided “gender-critical” women’s-rights advocates from strident trans-rights advocates. It also has caused schisms within feminism; and even within families, with some parents split over the best course of action for their kids. While this drama unfolds publicly in legislatures, town councils and on social media, it also takes a personal toll on those who’ve gotten caught up in this unusually vicious front in the culture war.
