Corporate social media has catalyzed divisiveness by filling our timelines with two things:

1. Content they know we agree with 100%. This produces an illusion of a cohesive "side" in our minds. Its the "us" in "us vs. them"

2. Content they know we disagree with 100%. "them" in "us vs. them"

Monetizing the system is the priority. Nuanced ideas don't drive clicks, tribalism does. Outrage and certainty are the de facto standards of the social media age.
