I thought this was interesting in Wiki
"Debating is also carried out for educational and recreational purposes, usually associated with educational establishments. The major goal of the study of debate as a method or art is to develop the ability to debate rationally from either position with equal ease"

Sometimes part way through a debate on here I do find myself seeing the other person's point of view so clearly it is hard to continue with objections to their arguments. This doesn't always mean that I agree with them but I perceive that with their life experience, educational level and personality type I can see where they are coming from.
When I speak of educational level I don't necessarily mean lack of formal education. Some highly intelligent and well-read people swallow the party line of academia whole and refuse to see any agenda beyond the fact that they are wonderful people looking for truth.
