Greenwald's fake news is his false description of Eichenwald's reporting. If you read Eichenwald's article, then you have all the "personal experience" you need to see that Greenwald is misrepresenting what he reported. And when you look up Greenwald's past, identical lies, you see that this misinformation campaign is deliberate. It's not a matter of opinion or of trying to judge competing claims. It's laid out right there in front of you if you want to look.
