That's a bad take.

The science mouthpieces (aka media and government speaking on behalf of scientists) were insisting they knew the immutable facts and any questions or doubt in those immutable facts were heretical. Anyone who has an appreciation of the evolving nature of scientific research should immediately see the red flags in that.

"Antivax" is not a position of anti-science, it's a slanderous label for an alternative theory with its own compelling evidence.
