Why did it take so long to figure out something so basic?
If I were speaking for myself, I would say: my problem is that for my entire existence I have been surrounded by sensible, decent, fair-minded, truth-telling people, capable of being reasoned with, starting with my excellent parents.
My problem is that I have always acted on the assumption that MOST people are trying to do the right thing MOST of the time.
My problem is I have never failed to observe that most people have mundane interests that respond to mundane give-and-take: bicyclists are interested in bikes, tires, roads; gardeners are interested in seeds, plants, soil; cooks are interested in recipes, ingredients, pots & pans; and all will relate with intelligence and fairness to those who have similar interests.
No matter what the religion. No matter what the language. No matter what the nationality.
Are there groups for whom this simply does not apply?
I still have hard time taking it in.
