Back in a more civilized time, editors took pains to “libel-proof” a story. If you knew you had something important to say, you had to make sure the target couldn’t win a lawsuit against you. You did so by making sure the truth was on your side and that you could back up your claims. If you were writing an opinion piece, like, say, “Evidence Suggests Taylor Swift Is a Sociopath,” your task was easier: The First Amendment is generous in protecting the right to publish opinions about public figures.
He straight up categorises mental health analysis an “opinion”, and not something that needs to be held to basic journalism standards.
