A lot of people are ok with lies if they confirm what they already believe.
The only people who care about "truth" in capitalism are shareholders and affluent individuals. It binds them to the culture and when a bunch of lowlifes and poorer people tell them "fuck off" essentially, they get pissy and upset that the people don't like the status quo.
These are the people that care about stability, in order to enjoy their wealth. A country that cannot agree with one another on objective reality isn't one that can be governed, and is destined to fall.
Which might be why so many of the "disinformation" fighters come from the establishment, and so many proprietors of distortions and lies are those with grudges (Greenwald, Bannon, etc.) or nothing to lose (QAnon/MAGA types).
It comes down to a difference between people that benefit from a stable status quo, and those (for whatever reason) that want to tear it down.
