To grossly oversimplify, we could state the blurred view proposed by the jokes being referred to as "All relationships are abusive".
Yes, it's amazing how easy it is to dismiss opposing arguments when you start by "grossly oversimplifying" them into something clearly false.
I didn't think I was dismissing an opposing argument; rather, pointing out that the article TimS linked to was making the opposite of the claim that you stated as a generalization of its point: not "these jokes express unstated general truths" but rather "these jokes express false generalizations ... and thereby leave significant distinctions unstated and, indeed, more difficult to state."
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
