Bob is clearly misinterpreting the devotion some fans have to certain franchises, which admittedly can come close to religious in their zeal. Nature abhors a vacuum and with Bob being a hard core secularist, it's pretty obvious that he was pop culture to become a new world religion to replace Christian traditions that he sees as being a relic of the "inferior" past. What is curious was how he views the Illiad as a blending history and mythology when the historicity of Homer is up to debate among scholars. A cursory glance at Wikipedia (use it for something other than looking up pop culture, Bob!) tells me that the Trojan War may have been remotely based on a conflict during the 12th century BC.
This is the thing Bob fails to realize: almost everyone in Homer's time were illiterate and people transmitted the tale of the Trojan War orally as written language was still in its infancy. Even most thinkers of Greek antiquity believed it to be a fable. What distinguishes the contemporary West from ancient Greece is that we have an extensive historical record and thus can see parallels between fiction and historical events. For example: the Galactic Empire from the Star Wars trilogy clearly took inspiration from Nazi Germany, which was still fresh in the public's memory thirty years after the Third Reich's defeat, and was still relevant as the Soviet Union took its place as the "evil empire" in the late seventies. Compare to the First Order from the sequel trilogy. It's supposed to be inspired by a supposed resurgence of nazism/fascist ideology in the West, but honestly better reflects the far-left's demented paranoia to the point where it borders on parody. When you peel it all back, it's easy to see Disney-era Star Wars and its embrace of Social Justice as cynical materialism.
If Bob wasn't such an insufferable clump of cells, I might feel sorry for how spiritually empty his life. He has to replace it with the shallowest pop-culture pablum his sausage fingers can grab onto.
