This is the issue. If you are already down a rabbit hole of beliefs you are going to keep seeing articles from news services biased towards your way of thinking. Things that continue to constantly confirm how you feel about the world.

In an ideal world news organizations would just provide both sides of a side, but unfortunately in todays world news agencies seem incredibly polarized and twist stories to suite their agendas. This now makes personalized news feeds even more scary and further contributes to the kind of polarization we see happening now. People seem more divided then ever in the last 20-30 years.
