From what I've seen, people find the news network they agree with and tether themselves to it.
I read news from a variety of sources. Sources with fact checking, editors and consequences for misreporting. I do not get my news at say...Foxnews because they employ very few reputable journalists. On the other hand I do read the New York Times because despite presence of op-eds I might disagree with, it is a world class news organization that generally holds itself accountable. I also like to read news sources that challenge my own personal biases. Perhaps that is not what others are doing but I would say that's part of the problem. I do however shy away from things that give me little information and serve mostly as opinion filler. Opinions are nothing special and people latch onto their own too much as if holding one automatically makes them immune to criticism. I think more people should probably start having this attitude if we want to reverse the decline of our nation and make no mistake, we are in decline due to this polarization.
Also let's all move away from labels - for example calling people ignorant is not going to move a discussion anywhere productive.
