There are fake news sites where you know the stories are satire, and then there are those that post fake news but don’t tell you, or at least not exactly. Rachel Alexander compiled a list of these, some of which are left-wing constructs created to trap Republicans into sharing fake news, or so the story goes.
Either way, these “news” sites do not (or did not) openly advertise any of their “reporting” as fake or as satire. When confronted by these ‘sources’ consider the content accordingly.
