How do we end the divisive mindset?

Society today is wrought with divisiveness. It's shown in the rhetoric that the media uses, and is ever present in our own thoughts and conversation. Even applications such as Facebook cater to this divisiveness with their content bubbles, supporting our confirmation bias and failing to properly educate us in critical thinking and analysis. I want to know what the community at HN thinks we can do to help end the divisive rhetoric and "information combat" that is occurring.
