Hi Mark, and welcome!
No offense intended to any believers on this site, but... looking at that web site caused a strange new thought to occur to me: People sure do put a lot of time and effort into the scholarly study of fiction. Historical fiction, perhaps, but fiction nonetheless. But then, I guess it shouldn't surprise me. People also put a lot of effort into learning to speak fluent Klingon, or Tolkien's Elvish languages; people put a lot of effort into being experts on a myriad of fictional civilizations and histories.
Again, no offense intended. Just a small personal revelation
