Exactly.  When something truly is desirable in the SMV sense, we just get long videos about how it shouldn't be.  For example, the people who think preference for blondes is because Mean Old Europeans forced their beauty standards on people who would otherwise prefer their women fat, big-nosed and with a short afro--never mind that medieval Islamic empires had the same preference with their harems.  Likewise with the belief that thinness is desirable only because of media and because it is supposedly a sign of affluence and high class--never mind that humans are hardwired not to want to fuck someone whose body screams "I'm very unhealthy!"
