This guidebook is designed to increase readers' personal resilience, self-acceptance, and growth from minority stress. Readers are encouraged to clarify their beliefs and improve their relationship with themselves to develop self-awareness, self-value, and self-direction. Conflicts can be resolved as readers develop knowledge of themselves and others and consider resilient ways of experiencing sexual and/or gender diversity. The LGBTQIA+ Peacemaking Book Project offers two guidebooks, Feel Secure in Yourself and Relate to Others with Confidence, and twelve e-resources self-published by each set of chapter coauthors. The chapter coauthors are scholars, clinicians, and/or community leaders, with differing and sometimes politically opposing viewpoints. They collaborated to find common ground, reduce prejudice, and improve LGBTQIA+ health and self-development for a wide range of readers. These self-help resources are written for the general public and can be used by academics, clinicians, researchers, religious leaders, parents, and other providers who want to learn updated and integrated ideas and skills about sexuality, gender, race and ethnicity, faith and purpose of life, emotional health, resilience, and relationships. This book project is a social experiment of bridge-building and hope to empower readers with identity and skill development and to reduce the side-taking that impairs growth.
