Thomas Westbrook, creator and host of Holy Koolaid, joins Mormon Stories to share his remarkable journey from growing up in an intensely fundamental Christian environment to becoming one of YouTube’s leading voices for skepticism, science, and critical thinking.

Raised by missionary parents and immersed in evangelical culture from childhood, Thomas recounts life overseas, homeschooling, Youth With A Mission (YWAM), purity culture, sexual shame, biblical literalism, and the constant pressure to evangelize. He explains how years of indoctrination shaped his worldview –and how education, science and asking difficult questions gradually unraveled it.

Thomas discusses the pivotal experiences that led him to leave Christianity, including confronting Young Earth Creationism, discovering contradictions he had never been allowed to examine, and realizing that curiosity was viewed as a threat rather than a virtue. He also reflects on the personal cost of deconstruction, including strained family relationships, fear of hell, and learning to rebuild his identity outside of religion.

This conversation also explores: growing up as a missionary kid and “third-culture kid”, sleep paralysis and supernatural beliefs, the role of science, evolution, and critical thinking in deconstruction, why Thomas started Holy Koolaid, exposing pseudoscience, misinformation, and religious grifters, Christian nationalism and religion’s role in modern politics, building secular community through the Faithless Forum, and what curiosity, uncertainty, and intellectual honest look like after faith.

Whether you’re questioning your beliefs, interested in religious deconstruction, or simply fascinated by how people change their minds, this episode offers an honest and thoughtful look at one man’s journey from certainly to curiosity.
