We’re already seeing it now, but any and all storehouses of previously uncontroversial institutional knowledge will just get labeled “liberal” over time.

It happened to Wikipedia, it happened even to the weather, it’s happening to nutrition, and given enough time it will start happening to things like astronomy, air traffic control, earthquake detection, scuba diving, etc.

Smartest comment in the thread imo. There can be good reasons for seeking a variety of ideologically leaned sources, but even the question of who is biased is a politicized question, and it won’t necessarily have anything to do with truth.

And as you noted, they change over time. E.g. “iraq war was bad” used to be considered an extreme far left position, though now it’s closer to a bipartisan consensus. “We need to avoid regulatory uncertainty”, “we need to curb judicial activism”, “deficits are bad” used to be right wing positions.
