I have had plenty of conversations with people irl. Most of the them with people who are to the right of me on the political spectrum. What I found in the conversations that were fruitful, was that our disagreement on larger issues, such as economics or personal freedoms, tended to stem from disagreements on smaller issues. To paraphrase my friend, "We are using the same words, but they all mean different things." It seems to me that there are some elementary differences between progressives and conservatives that change how we rationalize the larger issues. That's how the two groups can, based on the same information, come to two different conclusions.
That being said though, I think Fox News and other conservative news channels have created information silos. Not everyone who is conservative has necessarily had access to the same body of facts and evidence that progressives have. I think a good portion of people who are stuck in those silos would change their views if they had a more balanced news diet.
