Watched my friend get totally shut down at her mystery book club last month. She suggested the killer might have had a good reason in this thriller, and two members just talked over her saying she "missed the point." She hasn't gone back since, which stinks because she loved finding clues.
Did you see that article about how some book clubs fail because they squash different views? I remember reading that mystery authors actually APPRECIATE when readers debate the killer's motives, it means they're thinking hard. Your friend had a totally valid point, and shutting her down like that is just rude. Exploring why a character does something can be the BEST part of discussing a book. It makes me mad when groups act like their interpretation is the only correct one. No wonder she quit, that environment ruins the whole fun of sharing ideas.
Actually used to be the person wanting a single right answer, idk why. A friend kept arguing about a side character's choices in a book we read, and it drove me nuts. But then her take made me notice way more details I'd skipped, and it totally changed how I saw the whole story. Maybe it's just me but debating the gray areas is what makes a book stick with you.
