Media literacy is an extremely broad subject and includes everything from being able to summarise a text, to the discussion of themes within a work, to considering the arguments of a discursive or argumentative work on its merits. This is taught in UK schools.
Fake news, outrage bait, etc. is kind of a different beast, because you have to consider whether the author is writing in good faith as well as knowing a series of rhetorical tricks to look out for. This wasn’t taught to me in school.
