Answer:
In the most general form, fake news has three characteristics:
factually inaccurate
optimized for sharing
meant to obscure or distort with emotions; preying on prejudice or bias
A news story is not fake simply because it is impolite or inconvenient. A news story that challenges your beliefs or values isn't fake news. A news story that is rejected by those in power does not make that story a fake news story either.
