Agreed. It's a lie, and a particularly boneheaded one.

Is that occurrence enough to conclude that all their reporting, on everything, is flawed? Because if so I think I could find similar examples from effectively any mainstream source, and any partisan (HuffPo, Breitbart, et.c) ones as well.

Who exactly should we trust when our criteria exclude everyone?

No one said everything they do is fake news. I said it would be hard to have confidence in the data. Yuge difference.

So there is reporting from CNN that you would trust? What reporting is that?

That is an opinion piece at one of the Washington Post's blogs, the Volokh Conspiracy, it is not a news article. Furthermore, the blog authors are not Post employees and they are editorially independent from the rest of the newspaper.

That being said, I strongly believe that reputable news sources should not publish unmoderated opinion blogs from their own domain. No matter how many times the page says "opinion" or "blog" or "unaffiliated", if it's published on their site, on their platform, on their domain, it's going to be equated with that news outlet.
