You are right. That's the risk. However, art also has the quality of durability and long-lasting effect after its contemplation. The same problem, presented on a nespaper as part of, say, a denunciatory peace may have an inmediate impact but it is (more?) easily forgetable. I'd like to believe artistic representations can linger deeper in the audience and strike certain cords that may produce a change of attitude or awareness on the given subject.
This, of course, is also theoretical.
I appreciate your stopping by and commenting.
Have a great week
