>I'm not a trump fan, but the antivax train has nothing to do with him.

Well not nothing. But it predates him and he adopted the movement early in his political career. When I was in high school (2004-8) antivax sentiment was generally associated with liberal Democrats in places like Marin County. This was a favorite retort of conservatives when confronted with their own backwardness on scientific understanding of evolution and climate change. In 2015 Trump began courting the anti-vaccine crowd and the political valence of that flavor of woo-woo nonsense flipped seemingly overnight. It was surreal to see it happen in real time. By 2020 he had lost control of the monster he helped create and the crowd booed him when he said they should get the Covid vaccine.
