The event was hosted by John Safran, a legendary Australian media personality who has specialised in exposing religious stupidity over the years. He had a tv show called "John Safran vs God" . Most of it can be found on YouTube.
I was privileged to meet him and have a great chat! I shared our background as Jws and our journey from high control cult like belief to one of reason and facts. He was lovely to chat to.
This clip of his from a few years back was a great one! It exposes the irony of Door to Door preaching: (aimed at Mormons, but can be applied to us!)
