Maybe it's more of a UK thing-- a heightened sense of class consciousness?   It doesn't bother me if those who are fans of opera and classical music in general are thought to be elites.    Why should I care what people who hold that opinion think? I can converse knowledgeably on early rock, doo-wop, country, bluegrass, western swing, folk, sea chanteys, etc.--since I love a lot of it--in addition to classical music.

I wouldn't have much to say to somebody who thought that rap--or folk-- is the only form of music worth listening to--though a lot more to a folkie than to a rap addict. I'd just know that person is depriving himself or herself of a lot of pleasure.
