"Can you explain to me what an editorial editor is?"

In the case of the Washington Post, someone who routinely peddles lies and misinformation in order to influence public opinion to support pointless wars that end up killing hundreds of thousands of people.  140 articles in the build up to the Iraq War came from the Washington Post.  140.  Hiatt is still of course pushing the same lies and war propaganda that he did with Iraq, but his excuse is that this is an "opinion column."  Like the fake news which you claim is a problem, they simply take advantage of the readers media illiteracy because rather than a disclaimer of "Everything I say is complete BS" which would be more appropriate for his writing, they simply put it in the "editorial" section, taking advantage of people's ignorance.

Washington Post literally produces fake news by simply putting it into the Opinion Column.  If the fake news sites started doing that, would it magically become acceptable?  LOL!
