I have to confess that this thread title grates on my nerves a bit. Why should anyone have to gain the approval of others to like something? I happen to have very strong likes and dislikes but I don't give a toss what others might think of my preferences. I do, however, take exception to the 'I like all types of music' types taking over folk clubs. This is not because I disapprove of their wishy washy tastes but because I go to folk clubs to listen to folk music. This has got nothing to do with other people's preferences and every thing to do with categories and context. I doubt whether anyone would be very happy if they bought a book on, say, ancient history and when they got it home it turned out to be about gardening!
