Well, the source material is sketchy.
Wilfred Brimley

Almost all of the sources for the info on the Sandinistas are books/essays written by sociologists/historians and published by academic presses or peer-reviewed journals. Maybe you’re talking about the sources in the intro?Those are just to provide context for the broader discussion of women in combat, but even those are from the BBC, a peer reviewed journal, a couple of websites published by academics/institutions, etc. One is an essay by Alice Walker. I’m curious about which sources you’re talking about. Either way, all the stuff on the Sandinista women is from the types of sources mentioned above — sociologists, professors, etc. published in peer review pubs/university presses. I’m comfortable with those types of sources.
