I can't take Wagner, but I'm not daft enough to think I should despise those who do. I go along with the man who wrote "Wagner's music is much better than it sounds". The essential element in snobbery is not that you dislike some aspect of another person, but that you feel superior to them because of this difference.

And the snobbery is directed at the person rather than the cultural artefact. I don't think it is snobbish, for example, to despise The Sun, or in America, perhaps Fox News ( I go by reputation), but it would be snobbery to despise the readers or viewers. (Detesting them might be a different matter. It might be wrong, but it wouldn't be snobbery.)
