Maybe schools need to teach a little more about the world's religions, there was certainly nothing taught about them when I went to school.
Benefits of a Catholic education. We had comparative religion as an requirement. In the final year, we got to choose an elective option - my choice was Theology of the Devil. Not kidding. Reading list included C.S. Lewis' The Screwtape Letters, among other texts.
I've read most of the CS Lewis novels, including the Screwtape letters, but on my own. I'm definitely at a huge disadvantage in discussing religions with anyone.
I read almost anything I can get my hands on, but mostly old Science fiction stories and novels from the 30-s thru the 60's. I have a few thousand I bought from a estate that I put in alphabetical order by author, and added anothet thousand or so from other used book sales. I'm up to Delaney now, and might never read them all, although I've probably read 40% of them years ago.
Adorama, and our local camera store, Huppins (Onecall.com), are owned by Jews, but do not close on the Sabbath or other Religious Holidays, so obviously, their are varying degrees of how strictly they follow the rules, just as with all the other religions. I tend to admire B&H for sticking to their beliefs, and, since shippiing is not done on Saturday by most businesses anyway, its not a big deal when they are closed.
Off topic, do yourself a favor and jump ahead to the "W"s and read some Manly Wade Wellman.
On topic, my education on the subject was a college roommate who was both Jewish (Reformed) and the campus paper's main photographer.
Wakipedia has an interesting claim: "Surpassed only by the Diamond District in terms of Orthodox employment, the company is a vital part of the community's financial health, with hundreds of Orthodox Jews on staff."
