Rush is not a "shock jock"

Today's Observer refers to Rush Limbaugh and other "right-wing talk show hosts" as "shock jocks". This labeling happens all the time. So often, in fact, that I had to check to make sure I wasn't wrong in thinking that the term "shock jocks" applies to people like Howard Stern, not Rush Limbaugh.

I went to Wikipedia for an answer:

A shock jock is a slang term used to describe a type of radio broadcaster (sometimes a disc jockey) who attracts attention using humor that a significant portion of the listening audience may find offensive. The term is usually used pejoratively to describe evocative or irreverent broadcasters whose manners and on air behavior is offensive to the listener.

I'm sure Rush's politics are shocking to the editors of the Observer, but he doesn't engage in the vulgarity that is the trademark of the "shock jocks".
