They are the experts. They're the ones who live their day to day lives in pain and suffering. This documentary is more philosophical than anything. Forgive my arguing I am Agnostic so I'm not taking sides here but it would seem that the people to consult on an issue are the people who have to endure it from day to day instead of someone who's barracaded themselves in a building of education and has no interaction whatsoever with the pain of what it is to be in a low point in life. I know the main reason I left Christianity is mainly b/c of the persecution from people who had set themselves up as an authority on the bad deeds of Christians. I was so tired of turning the other cheeck every day, it just didn't seem worth it. Not to mention the fact that the only person who would actually try to connect to me was a homosexual. I believe this guy is the perfect authority to speak out. He's human like all of us. He's Christian (which is coming from source and not speculation). He's accepting of homosexuality (doesn't approve of it but accepts that all people are who they are). I'm sorry but I'd have to say he's VERY authorative of his material. It's dealing with philosophy and not science.
