The universal god is the product of theology. The perfect god is the product of theology. It isn't the product of actual cultures (most of us aren't academics). So all those criticisms apply to theologians. Too bad for them.
The popular gods of old, or now ... are much like their worshippers, as they always have. The Universal and Perfect god is a straw-man invented by theologians, and turned to other use by atheists. In other words, dishonest rhetoric.
And once again, semantics intervenes. I don't think Pop's notion of literal matches other people here, anymore than my notion of metaphorical matches other people here. People talking past people, at best.
Ancient people couldn't even read. Culture and religion were oral (see Oral Torah). Literate people produced literate religion, which is why whatever Moses believed, it was never written down. Same for Jesus and Muhammad. Wonder why?
And literate people were the upper class and the middle class that makes the predation of the upper class possible. People like Caiaphas (upper) and Paul (middle). Folk religion is ain't.
