Equating any criticism of the strategies pushed by the medical establishment as "antivaxx" is just as counterproductive as calling everything "racist" or "transphobic" or "homophobic" or any of the other epithets being bandied around by the new puritans. Words have meanings, these meanings can change over time (language evolves) but forcing them to change to fit a given narrative leads to an unhealthy political and social climate. It is what Orwell wrote about in "1984", what Solzhenitsyn wrote about in "The First Circle", what Bradbury wrote about in "Fahrenheit 451", none of which were meant as user manuals for a healthy society.
