The correct term would be "art can be political". It does not mean it has to be.
Nah, by definition art cannot be apolitical.
Politic is about trying to rule/influence over all parts of society, there is not a part of society that politic doesn't try to influence.
Art is all about sharing a message cannot talk about a subject that isn't inherently politicized and that the audience will not view through a political lens.
The notion that some piece of art can be free of politic is juvenile, counterproductive and rather myopic.
We can play that game too, name a piece of art and it's text/subtext and we will tell you how it's political.
Please don't choose something as easy as anything to do with love, war or transportation, you have to make it interesting.
