We could argue that people shouldn't make posts like these, but in doing so, we ignore our own humanity. We're not robots. Humor is an essential cognitive mechanism for building neural structures so that we can understand the world around us. It helps us to recognize and make sense of subjects that otherwise would be too emotionally difficult to face head-on. This is part of the reason I think that faux news shows like the Colbert Report have been so successful. By denying this sort of expression, we are essentially denying an important cognitive tool for understanding.
