Most people in the US know what 'talk radio' and Rush Limbaugh are about. For those of you who are outside the US looking in, the AM radio dial here is dominated by a chain of stations owned by Clear Channel.
The stations, for the most part, broadcast a steady stream of hatred of liberals, feminists (whom Limbaugh calls feminazis), environmentalists, Democrats... all you have to do is listen to some of Rush Limbaugh to get the idea.

There are many people who listen to this on a daily basis, getting only this type of broadcasting as their main "news source". The Limbaugh listeners pride themselves in being "ditto heads".

Recently, a man attacked a Unitarian Church, shooting nine people, killing two of them.
'''Police in Knoxville were quoted as saying that the man, later identified as Jim D. Adkisson, 58, targeted the church "because of its liberal teachings and his belief that all liberals should be killed because they were ruining the country, and that ... the Democrats had tied his country's hands in the war on terror and had ruined every institution in America with the aid of media outlets."
Might the shooter have heard talk-show host Rush Limbaugh say that "liberalism is the greatest threat this country faces" and "the Islamofascists are actually campaigning for the election of Democrats"

article, "Does shock jock hate speech lead to violence?" Shock Jock refers to the radio disc jockeys like Limbaugh who speak "shock" extremism.

quote from article "When I asked Rory O'Connor, author of a study of shock jocks and hate speech, for his take on the shootings, he replied, "Sure, these guys hold some responsibility for what happened, but we all hold responsibility - particularly anyone who hasn't stood up and spoken out against hate speech. We're all contributing to the climate where people are being dehumanized because of their beliefs."
