I think art is in the middle, while I have a lot of non-political work,
I'll point out that the reason I say "I'd like to see the arguments" is that...
Like...
I'll just go with one very basic example. Does (royal / general) your art feature the use of pink and or blue to denote any degree of femininity and / or masculinity? Either consciously or, if you stare at your (again, general / royal your, not aimed at you specifically) gallery long enough to vaguely some sort of pattern, unconsciously?
Political. Because there's a whole history of color association and whatnot and how / why they were used.
This is not to argue that Politics will be a
significant part of any piece of artwork, nor that they will be conscious / intentional or of a political subject that anybody will particularly take interest in (You are probably not going to get scaldingly hot takes dropping Ancient Egypt controversy on which particular regional interpretation of a god or gods is accurate, for example). Mainly that... frankly one would have better odds defining what is or isn't speech than they would claiming Art isn't Political. And one can make a
lot of arguments for what constitutes as speech.
Hell, for one more bonus example of Political Art: Just where you choose to post your art can potentially be - in and of itself - Political. We've had people explicitly refuse to post their content on sites like Twitter, Reddit, or so-on because of disagreements (or perceived disagreements) with the community (or perceived community), and "Intentionally do not share your art in [x] medium / forum" is a fairly textbook example. At this point the nature of the artwork itself is utterly irrelevant, yet it's still Political due to as much.
One could argue that this is a dilution of the word Politics... but if so the blame's probably not going to land in the lap (or timeframe) people think it will. The Degeneracy of Today's Youth (TM) is a thing that we literally have written records of people going on about all the way back to the days of the Epic of Gilgamesh, for example.
