I think this is kind of a reductive, attention-grabbing headline. The real intention is "stop equating 'the scientific process' with 'the entire body of knowledge that has ever been produced by people calling themselves scientists'".
The body of knowledge produced by scientists includes real truths, but also a lot of work produced by people without good methodology, and a lot of things that were thought to be correct at the time but were later disproved. And as the author mentioned, none of this is exempt from whatever society-level base assumptions were thought to be indisputable at the time.
For all that, the scientific process, while imperfect in many ways, is still the best way the human race has so far discovered to learn and advance. You could say that the pursuit of science is, by definition, the pursuit of truth.
