Mark Alsip, a former fundamentalist, shares his journey from religion to atheism and his deep concerns about the dangers of religious extremism. He discusses the importance of evidence and critical thinking in shaping his beliefs, a process that he believes can help prevent such extremism. Mark also highlights the need for a more inclusive and tolerant approach to religion, a stance that he believes can counteract the divisive nature of extremism. He emphasizes the importance of science education and the impact of climate change on our planet, issues that he believes can be better addressed with a rational and inclusive mindset. The conversation touched on the changing climate, its impact on the world, and the importance of traveling and experiencing different cultures. Lastly, I share my love for National Geographic and appreciation for the natural world.
