what does traditionalist mean? He's antivax. He should pasteurize either. I hope he doesn't take flu shots or even go to the hospital because that is just unnatural. Who need medicine when he can just eat tomato leaves.
In this case, it's just being a bit more risk-adverse on new things. He's not trying to prevent all people from getting vaccines, he just doesn't want them mandated until they've passed FDA approval afaik. He's against things like petroleum-based food colorings, preferring colorings that have existed in food and deemed safe over a long time. He's anti-heavily processed foods, and believes that the "food science" that has gone into making some unhealthy foods literally addictive do more bad than good, and that we as a society should spend more time banning and regulating those things for the betterment of our people.
There are absolutely lobbies he'll align with, just don't pretend that if he had different views there wouldn't be others jumping at the chance.
