If not, there is little point in debating.

Most liberals and moderate conservatives are content with CNN. The latter group thinks also accepts fox news, something that the liberals hate. Likewise, the moderates see msnbc as biased, while liberals like it. The far right seems to reject CNN in favor of Fox News.

Since all three groups don’t have a common news source, what is the point of a liberal debating a far right winger if they have no commonly accepted news source?
