The reason I said “not funny” is not my sideways way of saying “I don’t approve of that sort of thing” but is more related to the point in your second paragraph. You can’t just state your opinion in the form of a joke and turn it into a joke that way. (Except perhaps in some rare edge cases: “Knock knock. Who’s there? Epstein didn’t kill himself.”) It’s like if I said “What do you call a ladder? An accident waiting to happen.” Have I said anything funny, or have I just chosen a strange way to say “I think a ladder is an accident waiting to happen”?
And in the case of Bob, I can certainly imagine someone from another culture, or who is young and sheltered, etc. not being up on American stereotyping and for whom such innocence would not be merely affected innocence.
I have the vague impression that in spite of getting some obvious (to the outsider) things wrong (fervently believing the preposterous), Mormons or LDS culture get some less-obvious things unusually right (relative to non-Mormons/LDS culture generally). I’m curious about those things, how they felt from the inside, and how the rest of us look in comparison from inside that culture. What are some things you think LDS culture does well that the rest of us might be able to emulate?
