Should religion be taught in schools (optionally)?

I believe that schools and curricula should represent the communities they serve so the process is democratic and inclusive, not politicized and divisive. If schools taught conflict resolution, and offered assistance with mediation to the public, we could better address issues with school curricula and policies, with respect for democratic principles of due process of laws and equal protection of interests. In that context, schools and communities could decide how to handle issues if religion, sex and health education, the science behind the process of creation and evolution, and research on natural healing and the impact of prayer and forgiveness on health. I would recommend if not require training in conflict resolution, for school and public administrators if not for all citizens, in order to set up community based systems for addressing all other issues.
