It was a bit more complicated. It was a weird time. There was something that looked like science saying some scary things and there was a strain of skepticism about western medicine on the hippie fringe which, was on some level a left movement. But, more-so it was an anti bush movement than anything you would call leftist.

Then you had this whole strain of back to the land crunchy church conservatives that also bought into the anti vaccine stuff.

I know a lot of people who had kids during the height of the frenzy that fell into both of those camps. The circles overlapped a lot. The lefty-ish hippies mostly vaccinated in the time since. The churchy ones turned into trumpy antivax true believers. The circles do not overlap at all anymore.

For a short period of time around when our oldest was born, it was not crazy to be cautious. It was all debunked by the time our youngest was born.

FWIW, I make vaccines for a living and my wife is a scientist. We are not fringe weirdos. We vaccinated, though we altered and stretched the schedule a bit with our oldest.
