I don't think there's any real moral value in preferences--that is, cowboy songs are probably as enjoyable and worthy as opera and hokey movies are probably as enjoyable and worthy as arthouse movies. Tastes are so subjective and based on each person's personal experience and exposure. I generally hate unhappy endings and hate slapstick. There's probably some deep hidden meaning there, but I just tend to go with what I like.
Other than fringe stuff--porn, snuff-films, etc.--I can pretty much accept that most of the world likes what I don't (and vice versa).
I draw the line at people not liking Clay.
Batshit assholes.
