Please display your definition of "political" which makes sense in all our usual contexts but also makes at least some art unable to be viewed as political.

Sure, I'll give it a try:

> Something is political if it is intended to discuss, share or pomote certain thoughts on topics relating to behaviours or systems within a society.

The most notable difference of this definition to what you appear to understand as political is probably that it has to be intended to be political.

Someone eating meat doesn't intend to make a statement about consumption of animal products? Then them eating meat is not political.
