"I realize that protest paintings are not exactly in vogue, but I've done many"

This quote by Robert Indiana suggests that he is aware that protest paintings are not popular or stylish in the art world. However, he has still produced much of them. This could be translated as a declaration of his dedication to producing art that speaks with social issues, even if it is not popular or fashionable. It could also be viewed as an obstacle to the art world to acknowledge the value of protest art and to give it the attention it deserves. Indiana's quote is a suggestion that art can be utilized to make powerful declarations about the world and to bring attention to crucial issues. It is a call to action for artists to utilize their work to make a difference.
