So you've helped what I consider the problem of social media and targeted everything: you decided to reinforce your echo chamber.
The problem with everything giving you suggestion based on your previous behavior (from Netflix and Youtube to Amazon) make people never even see new things and philosophies. The only way they get a view of "the other side" is through the exaggerated prism of their own side. Recommendation engines should start to let a little percentage of their suggestion be really different things or thought appreciated by people you have nothing in common.
Just as a thought experiment: read a description of whatever group you associate with from some opposite media / blog. See how they'll tend to cherry-pick and misinform. Then go back to your usual media and how they inform you.
