It goes back to when someone looks upon a great creative work and remarks "Now, this is Art!" Clearly they are stating the obvious. Of course it is art. But the implication is that the art is good or exceptional to receive that remark. When we say "Keep politics out of X." We mean, keep your low level surface level read and its corresponding ill-informed utopian solutions you thought up in grade school to yourself. Do it good or go home. They opt to do it bad and complain when no one cares they are hacks.
