"But... not everyone agrees with the Chantry," Hermione replies, looking genuinely puzzled. "I've heard of theocracies before, but they can't really get off the ground if there are people who don't agree with that theocracy's basic canonical law."

When Mia doesn't answer her question, Hermione simply looks at her expectantly for a moment. When no answer comes immediately, she tries to rationalize it by parsing out the semantics. "Annul means invalidate, doesn't it? To legally void the existence of a particular law or act?" She's never heard of trying to annul actual people, and so any such thought is far from her mind.
