I tell this story to emphasize that it isn’t just Facebook that has a fake news problem, and it isn’t just Donald Trump and kids in Macedonia who are using social media to send the news spinning wildly away from the truth. When sites like the Huffington Post post partisan clickbait that is clearly untrue, they deserve to be shunned, not reshared.
