(PS -- just asked Larry, who went to Catholic High School, where the subjects covered in public school were covered in more depth, and he too says there was no mention at all of Asian History, much less of comparative religions or eastern religions. So, perhaps it's a function of this Bible Belt. We went to the same university, and he doesn't recall anyone taking Asian history. I'd like to imagine that it was offered, but I wouldn't be surprised if it wasn't. I took a World Religions course there, and I recall the professor constantly making apologies to the Christians in the class. If Journey to the West was ever mentioned, it was glossed over and I don't recall it.
Larry's father, who was in his 40's when Larry was born, served in the Chinese-Japanese War and then his whole family was in Pearl Harbor when they were attacked. [Larry born much later, in 1951.] It's as if these wars were the first they knew of "Asians". Yes, that's absurd, but I'm trying to paint a picture. Even John, who is younger than Larry's people, does not want to know a thing about Asian history or culture. He'll get mad if you try to tell him anything. John was a life-er in the Navy - early Vietnam era and afterwards.
So at the moment, I'm thinking Bible Belt + Military culture are behind the lack of information. The "enemy" and all that.)
What I'm describing may not have been true for subsequent US generations. Perhaps Ellen, Jennifer, or Nick were exposed to that which I missed, decades later.
