Talking to Kids about Gender Identity

A Roadmap for Christian Compassion, Civility, and Conviction 

As gender identity, transgender experiences, and emerging gender identities continue to be normalized and celebrated, many parents are left struggling with what to think about these issues--let alone how to talk to their children about them.
