One of the Globe's alleged readers wrote this letter as a commentary. A number of people have suggested that the Globe falsifies letters, but I wouldn't know. I certainly know that they have never printed one of my letters.
You are correct that they make up letters. My Ex's first job was part of a 14 person staff for the Copley press that did nothing but write letters to the editor. They were off the official payroll. Copley Press owns the SD Union. This was back in the 70s and I don't believe the practice has changed. They would be given marching orders how to slant the letter depending on the editorial department leanings (make the writer look stupid if was against the paper's position or be brilliant if it supported the position). They were paid by the letter submitted. When a newspaper wants controversy, they will create it. Therefore, look on any letter-to-the-editor with skepticism whether it is really from John-Q-public or the paper’s editors.
