Very recommended for a SOF show would be Norman Phelps. I heard him speak at the "Their Lives Our Voices" convention last year and was immensely impressed at his eloquence and knowledge. His speech was remarkable and you could of heard a pin drop...
Norm Phelps has been an animal rights activist for more than twenty years, working with a number of animal protection organizations. He is the author of The Dominion of Love: Animal Rights According to the Bible, The Great Compassion: Buddhism and Animal Rights, and The Longest Struggle: Animal Advocacy from Pythagoras to PETA, published by Lantern Books.
I think a SOF show with Norm would be an amazing thought provoking event!
