Comparing changes in nuclear doctrines with people choosing a different way of life (granted, also for their children) than the majority seems totalitarian, to me.

Minorities are, well, in miniority. Noone is at any point waging "everyone's supper" by trying out alternative ways of farming within their small miniority. (Meanwhile the majority IS risking everyone's supper in some decades).

Nuclear is different from your other examples because the choices of a small minority can drastically affect the vast majority.
