How ironic that you chastise a critic for interpreting it as allegory for some of our modern predicaments, and yet in the same breath defend it as an allegory for a historical event.
Most fantasy, including Tolkien and post-Tolkien, is best understood as a distant descendent of the epic poem. Essentially, it celebrates some kind of 'heroism' in a very romantic understanding of the term, and details a series of events which are crucial to shaping the culture and history of a people. The vast body of literature on epic poetry is enough to indicate that they can both rely on verisimilitude and present complex allegories. Ovid's Metamorphoses contains both references to historical figures and events (Julius Caesar, Pythagoras) and many of the legends of Greco-Roman mythology that are best interpreted as allegory (Proserpina, Orpheus, Midas). Don't be so fast to decry people for reading contemporary fantasy also as allegory.
