Maybe it’s that we made the Internet so full of disinformation that everyone is just automatically refusing to listen to others,

We've made a vast social space where people can get validation and acceptance as easily as they can choose to be challenged and face threats to their own sense of self importance and their egos, and this isn't to sound disparaging, we ALL have sensitive egos and all feel a resistance to facing challenges, so what will we all choose over and over? It's natural that we seek the path of least resistance that also boosts our positive feelings about ourselves.

We're not a rational or reasonable species, we use rational and reason to explain our emotions but those explanations are rarely accurate or based in reality.
