Aesthetics is very much political among other things. Arguing that an image doesn’t have power flies in the face of the prohibitions on images in the Judeo-Christian law.
I suggest that you read some aesthetic theorists, starting with Plato, and immerse yourself in the history of the debate about the power of images. Art history courses generally don’t use systematic aesthetic theories to undergird their surveys.
Trump has a lot to be ashamed of as a human being, and I take the body shaming (ie his corpulence and small flaccid penis) as visual metaphors for the hollowed out Trump name and brand. But what art means and says is ultimately personal to the viewer until some right thinking individual like yourself tries to tell us what to think.
