A movement with a distorted sense of individual rights that would seek to hamper vaccination in the midst of a global health crisis is reactionary to the core and hostile to human life itself. The dangerous rise of the anti-vax far-right is a symptom of a sickness in this society that we will still be confronting well after the last wave of the pandemic has finally receded.
That’s a dangerously broad definition that effectively describes almost every modern political party today. Most people want to protect their community, both from threats internal and external. When Joe Biden talks about his need to protect the “soul of the nation” from an outsider like Trump, that fits your definition exactly. When Democrat activists argue they need to punch conservative political pundits for saying things they don’t like, that fits your definition exactly.
