"Reason is a slave to the passions" -- David Hume.

There is objective truth to be found, outside of say, abstract mathematical entities. Within the context of human affairs, culture and politics, it's just subjectivism all the way down. The belief that information can be "neutral" is actually nonsense.

This is sometimes referred to as the "false balance" fallacy. But it's just epistemically true. At some point when you're constructing a narrative of the world, to communicate what you think is true, you're going to bring some subjective starting axiom into it (probably unconsciously) in order to bootstrap the whole process of reasoning through a cognizable narrative.

For society to even function, we have to ultimately have some shared subjective assumptions, otherwise all social cooperation becomes impossible.

At some bedrock, foundational, bare metal level, communication between human beings that yields a productive transmission of information, is dependent on bias. You couldn't even begin to have a shared understanding.
