It's not very useful to stress that they're "artificial" unless you're trying to introduce the term for rhetorical effect, say, edging it into the discussion on narrow or technical but not especially useful or broad applicability, relying on implications of the word or other, far less relevant meanings or shades of meaning to have an effect on listeners/readers. This happens a lot, especially in political discussion. It's sloppy as hell and should put you on high alert if you catch someone doing it, especially if they should know better.
