> Sounds like you just want scientists and researchers to share your ideological biases.
Not at all. My dad worked in public health, and I grew up around extremely liberal northeastern white people who worked in Africa and Asia while adapting themselves to the moral environment of wherever they happened to be working. You'd never know from their work they had any beliefs other than "vaccines are good" and "pregnant women should get sufficient folate."
> Who would be the arbiter of neutrality?
The public as a whole. Either they perceive you as neutral or they don't.
> "Wipe out"? Absolutely abhorrent and authoritarian take.
Public health as a field needs people who prioritize institutional values to the exclusion of everything else, because that's the only way you can build trust across the whole population. People who "bring their whole selves to work" endanger lives by destroying confidence in the public health system. If they can't do what the job requires they must leave.
