Here's a hypothetical example of confected outrage. Suppose politician A wishes to attack politician B.
Politician B parks in a no-parking zone and gets ticketed.
Politician A gives a speech saying "Now, you may say this is not important, but it speaks to the issue of character. Character, my friends, character. Character is everything. We are a nation of laws, not of men, and what does it say when politician B arrogantly thumbs his nose at the law of the land? I would call your attention to the fact that politician B's office at first denied the report. The issue is not just the crime, but the cover-up. Politician B's office lied to the people, lied to you and lied to me, and I ask you: what will he do in office? Will he continue this persistent pattern of unending scandals, lies, and cover-ups?"
This is confected outrage. Politician doesn't actually care about politician B getting a traffic ticket, but by pretending to be outraged he hope he can arouse real outrage in the voters.
