So you don’t think religion often drives a wedge between groups of people that otherwise would live together without issues?

Is that what I said? Don’t strawman me.

Let me put it this way instead: given any system of self-replicating information, be it DNA or gospel, you will observe convergent evolution. If the environment offers a productive niche, then it’s only a matter of time before that niche gets exploited. Monotheism isn’t a tragic freak accident – it’s an inevitable response to an unexploited niche. Wishing it away is pointless because then something nearly identical would spring up to replace it. If one wishes to alter the reflection (i.e.: culture), then they must direct their focus upon the subject therein (i.e.: human society)
