That’s it, “schoolmarmish.” But I see it differently—she talks to other adults as if THEY are third-graders, and have to have every simple concept explained to them. It’s right there in her ‘clarification’ of her “I inspired Occupy Wall Street” spiel. “No, you stupid person, now I will explain what I REALLY meant,” she seems to be saying, as she completely alters her original meaning.
