I will write off someone's love of something I consider cheesy or ridiculous as being a quirk that doesn't make them in any way inferior to me. I have my own favourite uncool songs or happy-making mind candy -- I don't really feel the need to be highbrow 24 hours a day, or even 2 for that matter. Being conversant with Puccini's operas or the entire works of Tolstoy doesn't make anyone better than anyone else, it simply means they've been fortunate enough to be exposed to such things in a way that appealed to them (and sometimes, it just makes them a bit of a twat who "likes" things because they think they ought to in order to conform to a certain "type").
It could be worse
