Stephanie Zvan's parents decided they wouldn't raise their children in any religion.

Coming to religion as an outsider, Stephanie doesn't have much interest in theology or apologetics. She'd rather get on with creating that post-religious world the demographics tell us is coming.

Abby Hafer is a speaker, writer, and humorist who particularly loves taking on Intelligent Design, Creationism, the politics surrounding them, and science denialism in general.

A few years ago, she realized that Intelligent Design is a political pressure group, not a scientific issue. With this figured out, she realized that what we need are political-style arguments in defense of evolution. Her presentations contain bulletproof science, but are short, easy to understand, easy to repeat, and make the opposition look bad. She uses humor to puncture bad arguments. Crucial questions are raised, such as “Why do mens’ testicles have such a bad location?” and “Who does God like better, us—or squid? Once she mentions testicles, everybody pays attention.

She has written a book titled The Not-So-Intelligent Designer—Why Evolution Explains the Human Body and Intelligent Design Does Not which was published in 2015.

Dr. Hafer has a doctorate in zoology from Oxford University, and teaches human anatomy and physiology at Curry College. She is a former DJ and loves doing radio and TV.

Indie folk artist Shelley Segal uses her music to create the world she wants to see.
To reflect, challenge, comfort and inspire herself and her audience

The rootsy singer songwriter and guitarist is a seasoned tour warrior, honing her live show at bars, clubs, festivals and lounge rooms across Australia, UK and North America over the last 5 years.



Shelley grew up in Melbourne, Australia, in a religious community. As young adult she questioned her Jewish tradition with it’s strict rules and rituals which separated men and women.

Through her music, Shelley has become a staunch human rights advocate which grew out of her anger with those strict rules and regulations that especially affect women and those who want to live on their own terms.

Shelley’s songs relate to her journey, discussing issues of religious freedom, tribalism, and women’s issues of rape culture and inclusion over mercurial vocals, spirited and soaring one moment and the next, bottomless; growling out lyrics that poke and prod and never leave

Carter Warden is a former conservative worship pastor of 25 years, now openly atheist. Having been involved in music nearly all of his life in church choirs, leading worship bands and being the lead singer in a Christian rock band, Carter is now writing and performing secular songs. His songs cover relevant topics such as using reason and critical thinking, the separation of church and state, leaving religion, the pressures of coming out publicly, creating meaning and purpose, and living a life of wonder.
