We do live in a culture of monist idealism. We assume ideals to be universal, rather than unique.

For example, a spiritual absolute would be the essence of sentience, from which life rises, not an ideal of wisdom and judgement, from which it fell. One is elemental and the other is aspirational. Hence all the political movements and ideologies evolving in the shadow of monotheism and its political expression of monotheism tend to see their ideals as unquestioned absolutes, from the Terrors of the French Revolution to the current cancel culture.

Good and bad are not some cosmic duel between righteousness and evil, but the basic biological binary of beneficial and detrimental. The 1/0 of sentience.

Yet because our culture is built around seeking the ideal good, conflicts tend to become a race to the bottom, of us versus them and any nuance or discussion is forbidden.

The real ideals, trust, honor, love, respect, responsibility, etc. are emergent from our growth and calibrating our desires to our situations. Judgement is what we do, not what we are told.

Desire and judgement. The heart and the head.
