Actually it's monolithic thinking. Obviously the other side is just bait.
Democracy and republicanism originated in pantheistic cultures. To the Ancients, gods were what we would call ideals, memes, metaphors today. Gods of war, love, beauty, sun, stars, etc. Essentially the foundations of logical thinking and communication. The focal points of reference across society.
To the Ancients, monotheism equated with monoculture. One people, one rule, one god. Politically expressed as monarchy. The Big Guy Rules. Ancient Israel was a monarchy.
The origins of the Christian Trinity go to fertility rites. The young god born in the spring to the old sky god and the earth mother. Though by the age of the Olympians, Zeus didn't give way to Dionysus. Tradition prevailed over renewal. The old didn't give way to the young.
Which is why the story of Jesus, crucified for questioning the establishment and risen in the spring, had such fertile ground to take root.
Though by the time Constantine adopted it as the state religion of Rome, it too had started to calcify and so the monotheism served to validate the Empire rising from the ashes of the Republic. The Big Guy Rules. While the origins of the Trinity were shrouded by the Holy Ghost, as the Church didn't do renewal, or women.
As such, the Catholic Church was the eschatological foundation for European monarchy. Divine right of kings. As opposed to consent of the governed.
When the West went back to democracy and republicanism, it required separation of church and state, culture and civics.
The logical flaw in modern monotheism, the "all-knowing absolute," in the words of Pope John Paul 2, is that ideals are not absolutes.
Truth, beauty, platonic forms are ideals. The core codes, creeds, heroes, narratives at the gravitational center of every society are ideals. Without which they would break apart and be scattered to the winds. Tower of Babel.
The universal, on the other hand, is the elemental. So a spiritual absolute would be the essence of sentience, from which we rise, not an ideal of wisdom and judgement from which we fell. The light shining through and animating the film, than the stories playing out on it.
When one assumes one's own ideals are absolute, then everyone else must be false. Not only does it apply to the various religions, but every ideology arising in the West, from capitalism and communism, to liberals and conservatives, feel they must assert total compliance, or be dismissed as relativistic.
Morality is not absolute, as it couldn't be transgressed, if it were, like a temperature below absolute zero. Morals are the ideals that enable a healthy society. Such as one's worth and status a function of what one adds, not what one can extract. Imagine a village trying to exist, if everyone just grabbed what they could. That is why our society is so necrotic, but to peel away those layers, would require going to the foundations and for most people, it is a language they just don't understand.
