If the nature of a thing is an ultimate fact, that means it is for all practical intents and purposes identifiable as a single item, and that it is defined, is real, and that it is irreducible. Nothing more required. If the thing satisfied as to 1 and 2 but not three, then the fact is still a fact, but must be qualified by its dependence. All else is opinion.
Fake news does not understand this. It presents things nit identifiable without proper definition and without qualification if required, as fact. Otherwise, fake news with take an ultimate fact and claim falsely that it depends on other things I.e "alternate facts"
There is no argument but that current Republicans are the greatest purveyors of lies in US history.
