Maybe the social, cultural and biological implications should be explored a bit further.
For one thing an intolerant social ideology is a monoculture. Either you are one with the group, or you are outside the group. As individual bodies, we function as monocultures, otherwise the immune system kicks in. It is the nature of the organism to synchronize its functions, in order to function as one.
On the other hand, an ecosystem is a multiculture, in the sense that all the various organisms harmonize their activities, in order to fill out the various niches and utilize the resources.
To the extent organisms function as one, they rise and fall as one. While within ecosystems, some are rising as others are falling, in an overall equilibrium.
So monocultures do arise, but they also generate blowback, consequently are limited in their durability.
Consider that a spiritual absolute would necessarily be the essence of sentience, from which we rise, not an ideal of wisdom and judgement, from which we fell.
Conflating the ideal, which is aspirational, with the absolute, which is elemental, creates the belief that one's ideals should be unquestioned and even though formal monotheism has faded, the long shadow of absolutist ideologies continues to haunt Western civilization.
The Ancients were not ignorant of monotheism, but as there was little distinction between culture and civics, it equated with a monoculture. As in one people, one rule, one god.
Remember that democracy and republicanism originated in pantheistic soceties, as that was how they framed the multitudes of forces and influences permeating the natural world and human societies, such as both gods and goddesses.
The Romans adopted Christianity as the Empire solidified and any remnants of the Republic were shed. Consequently the default political structure for the next 1400 years was monarchy and feudalism. When the West went back to more populist forms of government, it required separation of church and state, culture and civics.
So under these philosophic conundrums is a bit of history and basic physics.
