but it is important to remember that there is more that we agree on than disagree on. i don't agree with doug very much but i agree with everything he said in the opening comments there. there is a need for civility. we can agree to disagree respectfully. >> shannon: any clue why it's so different now? britt hume talked about the rhetoric so hostile. >> the ideological extremes have come to control the political dialogue and the message. it's very sad. when i grew up there was a sense that politics ended at the water's edge. we were the united states of america, the greatest country and we would come together around issues like civil rights, medicare, medicaid. that's all gone now. we are in a zero sum society where the winner is fighting against a loser, good versus evil.
