I find it very useful to frequently ask the following questions: “What are this person/position’s base values and core beliefs? What are they trying to achieve?”
We know that beliefs are empirically testable, and that values are the expression of physical and psychological needs. Once we address them directly, on a case-per-case basis we can come to solutions, rather than -isms. Ideologies are merely tools to try to understand the world, and meet our needs. You’ll never find one that is “true” or “right” or “perfect” in anything other than the most specific context.
