Anti-vaccine Equivalence Fallacy

The stronger fallacy of claiming that any questioning of vaccine policy is equivalent to being anti-vaccine, or that all vaccine-hesitant positions are equally baseless. The anti-vaccine equivalence fallacy erases important distinctions—between those who reject all vaccines and those with specific concerns, between those who are misinformed and those who are persuadable, between questions asked in good faith and propaganda spread in bad faith. By treating all deviation from consensus as equivalent, the fallacy prevents nuanced discussion, alienates potential allies, and actually strengthens the most extreme positions by lumping them with moderate concerns. The equivalence fallacy is beloved of activists who prefer condemnation to conversation, and of those who find it easier to stigmatize than to persuade.

Anti-vaccine Equivalence Fallacy Example: "The health official committed the anti-vaccine equivalence fallacy, saying that anyone with questions about the new vaccine was 'just like the anti-vaxxers.' Parents with genuine concerns felt dismissed and became harder to reach. The fallacy had created the very resistance it claimed to fight. Nuance was the casualty."
