"Tolerance, a term which we sometimes use in place of the words respect, mercy, generosity, or forbearance, is the most essential element of moral systems; it is a very important source of spiritual discipline and a celestial virtue of perfected people."

Do you think that each individual's private notion of "things you just don't do" is fundamental?

Or do you think that we derive our individual "don't do" lists from something else?
