That’s a good analysis: opinion vs. conclusion. That’s why when confronted with a conclusion backed with data, they start using insults. Their ‘opnions’ have no foundation.
That's right. When I want to introduce an understanding of subjective values vs. objective principles, I use the following example.
Let's say I'm wearing a new sweater. Ann thinks my sweater is pretty. Barbara thinks it's ugly. Neither of these opinions is either right or wrong--they're both based on the person's subjective perception of what's pretty.
But if Ann says my sweater's made of 100% silk, and Barbara says it's made of 100% cotton, they're now dealing with objective reality rather than subjective values. They are either right or wrong, based on the fact of my sweater's fabric, not on their opinions. They can both be wrong in this case, if my sweater is in fact made of wool, but they can't both be right, because my sweater can't be both 100% silk and 100% cotton.
