Seth King's opposition to gender-affirming care for minors under 18 reveals a principled stance rooted in concerns over consent and potential long-term health risks.

His unexpected alignment on this contentious social issue with more traditionally conservative factions suggests a highly localized approach to policymaking, potentially driven by regional New Hampshire values.
