Don Jefe — I’m not a Bernie Bro and I, too, would like to see the sources. Why? Because I’m a librarian and teach information literacy to students. The author obviously did a lot of research; I am not disputing that. Listing the sources would make it easier for the rest of us to have something more to point to when making similar arguments. Could I look it all up myself? Yes, of course. That’s not the point. The point is that when you make these arguments which are important and deserve to be heard, they will be taken more seriously by those who are prone to not accept them if you also list your sources (and show a variety of well-researched sources).
