All art is propaganda. It is universally and inescapably propaganda; sometimes unconsciously, but often deliberately, propaganda.

As commentary on the above, we add, that when artists or art critics make the assertion that art excludes propaganda, what they are saying is that their kind of propaganda is art, and other kinds of propaganda are not art. Orthodoxy is my doxy, and heterodoxy is the other fellow’s doxy.
