I got about 11 pages into the PDF (thanks for sharing).
It looks like the sort of agenda-driven pseudo-scholarship I encountered when I was working toward my MA at UT El Paso. Although some of the details and citations might be new, but the gist of it is the same stuff with which I've been familiar for decades.
Yes, Mexican cowboys were important to the development of the cattle industry and to the culture which we now identify as the American Old West. But, to be brutally honest, they are footnotes to history, and not much more.
Footnotes are fascinating, and often quite engaging as they present new material upon which we can attach our imaginations. After all, if most of us were to admit it, after a few decades we've all pretty much heard all we need to hear about Billy the Kid, the James brothers, Tombstone or Deadwood. Fresh blood is fun. So having some new stories from the Mexican side of the border are fun for fueling game ideas (as well as fiction and so forth). So, the new stuff might be a fun diversion, but contrary to the SJW author's attempts to affect the core of American Western Identity, it does not.
It just adds a little bit of spice to an already tasty dish.
So, I'll say it like this: Footnotes aren't history. And this work is nothing but one big, agenda-driven footnote.
(BTW, I looked up the author's credentials online – she would be very comfortable being called an SJW, and would doubtless not take it as the pejorative that I intend it to be.)
