Eh, I wouldn't be so sure. I tend to think there are three groups of people when it comes to media literacy:
1) People smart enough to recognize good and well-researched journalism (they already knew WaPo was legit)
2) People who just don't give a shit either way (they're not even reading this story)
3) People who would believe that this story is itself a planted piece against conservatives, funded by a liberal version of Project Veritas, and of course aren't even reading the story because it's on the Fake Washington Post.
Group Three scares the shit out of me. Group Two just makes me sad.
