Manufactured Outrage
A falsified righteous outrage at things that are basically unimportant and meaningless, frequently employed by politicians, political activists, or the media. Politicians and talking heads use it to garner support for their causes, to claim the moral high ground and to tar their opponents; the media often just uses it in a cynical bid to increase ratings.
Manufactured outrages of note include Nipplegate, the Monica Lewinski scandal, the 2009 tea partys, backmasked satanic lyrics, lapel pin controversies…
Just about any time you hear any politician, activist, or radio show host getting outraged about anything, really. The louder and angrier they get, the harder they’re working at manufacturing it.
