Seems clear the author: 1) knows next to nothing about Middle-Earth or Tolkien's larger work and honestly admits it, though continues to make sweeping generalizations about a subject they admittedly know little about; 2) knows nothing about classics, ancient history nor history of technology except perhaps bullet points gleaned from a pop documentary, iow, author displays extremely pedestrian and shallow knowledge or understanding of these vast subjects; 3) has taken at least one high school level course that included discussion of the Industrial Revolution; 4) likes guns, maybe owns a gun, has no great reason to own or use a gun other than childish affectation or perhaps even obsession.
It should also be said that the bloggers writing style is profusely insulting, almost like they're intentionally sabotaging anyone's ability to take them seriously, even if the question could have been interesting, instead the author indulged their immaturity.
