I agree.

I would go so far as to say that beliefs divide people. They just do.

To come together as a species we need a universal ethic that can govern personal interactions, the political process, the economy, and even relations among nations--yet can still allow for personal beliefs that don't contradict that ethic (such as the belief that we should love one another). We can call such an ethic the ethic of justice.

To be universal it cannot involve even one belief. That leaves as our only option a strictly rational ethic that follows from observation within material existence to serve as our ethic of justice: "Real Justice (summarized for a '5 min read')" here in Medium.
