Ahh, a rewilding book club, now that sounds good!
Not having read it myself, your description of the struggles you're encountering brought up an image in my mind, where you draw the various chapters/topics and the "leaps of faith" as arrows with a short description. So too for the division/categorization and your apprehensions thereto. Perhaps even using different colors to jot down where you share the line of thought and where you don't.
Hope this helps.
