Atheist Experience

The Atheist Experience is a long-running Austin-based atheist radio show that debates atheism via call-in listeners. It's rather famous. Matt Dillahunty is one of the hosts and is a very accomplished debater (Ken says that Matt Dillahunty is the best he has seen).

The following quote is from their website as of 5/6/2013.

The Atheist Experience is produced by the Atheist Community of Austin. The Atheist Community of Austin is organized as a nonprofit educational corporation to develop and support the atheist community, to provide opportunities for socializing and friendship, to promote secular viewpoints, to encourage positive atheist culture, to defend the first amendment principle of state-church separation, to oppose discrimination against atheists and to work with other organizations in pursuit of common goals.
