As this is HN, I really believe that this lack of a shared reality is only possible with the Internet. Before the Internet, there were more conservative sources and more liberal sources, but never before could you completely surround yourself with your own version of reality. And more importantly, your version of reality is constantly reinforced by algorithms that are specifically designed to raise your level of rage (aka "engagement").
I certainly don't know what the right answer here is, or even if there is one. The flip side of this polarization is the Internet has allowed discriminated groups to organize (e.g. see the "It Gets Better Project")
