I dont think either of you picked up on his subtlety--
He said "popular" media-- eg, things that some not-insignificant portion of the population will find favorable on some level.
For a reasonable example; Red Dwarf. It was a "loosely science fiction" (ahem) show produced in the UK, which has a cult following. Some percentage of people just freaking loved it, despite it being a droll waste of airtime in many respects. (Bagging on it for devil's advocate here. I actually did enjoy the series, just not to the point of excessive fanboisim. I took it as a modern satyr comedy, just minus the satyrs. Ideally, I feel it should have followed something like StarTrek in the time slot, but hey, the media executives had their own views.)
Somebody seeing it for the first time, and thinking it was supposed to be "serious", could well have apoplexy and rail endlessly about how utterly horrible it is, while failing to understand that such horribleness is exactly the point of the series, and many people LIKE the horribleness.
I believe Arx is trying to make you see that just because ONESELF does not like something and has a terrible reaction to its very existence, does not make that thing unworthy of being, or of being enjoyed, especially when that thing has defacto gathered a following (Due to being popular.)
A less meda-centered example might be social networking. I personally despise FaceBook. I want it to die like MySpace did. I wont wax philosophical about how people who use FaceBook are horrible people, because that is elitist horseshit-- People use FaceBook for a variety of reasons, and if they enjoy giving away all their personal information to every 3 letter agency on the planet, so be it. Who am I to judge them as people? I can dislike the thing, without disliking the the people who do like the thing.
