CNN spent considerable effort to ID this guy, not because he was a racist but because he made fun of CNN. So the premise of this article is flawed from the get go.
But ignoring that, is it CNNs job to troll the internet, finding what they deem racists on YouTube, Facebook, etc and threatening ruination of their life if they do not mend their speech according to CNN standards? Is this what is taught in journalism class, is this the new ethics of journalism? If so there could be one hell of a media DOX war, since there is plenty of offensive vitriol spewed from both left and right to give media outlets the excuse to dox.
CNN stepped into such a large pile of poop, I do not think they have any idea.
