Is this the dialectic that Karl Marx spoke of?
Trying to discover truth by considering ideas together with opposite ideas may work in philosophy where you are actually interested in the truth, but in post-Palin America - where paid "news contributors" have studios built in their houses by the very network that pays them for their opinion - modern "debate" only ensures a continuing argument where both sides cancel each other out as they trumpet their fairness and balance.
"IT'S A BUSINESS." Not fair. Not balanced. Dangerous.
