bias does not imply incorrect or factually inaccurate. "trump assassinated world leaders and triggered a full blown war in iran" is not bias. its factually accurate. That it breaks with someones worldview is not bias. And we need to stop pretending that adhering to objectivity is "bias".
By that definition, all medical science is "biased". And until the current administration, it wasnt. Requiring people making claims to demonstrate it with repeatable methods is not "bias".
