What would you call it when you have so strong feelings about what people you will never meet or even interact with think about a marginal feature of English? It certainly doesn't seem very sane. And it's not even that they are wrong, "murder of crows" is definitely correct English. Not just very commonly used. By the way, asking crow researchers what terms they use is just silly, they are the least likely to be using it, it's not a technical term, it's a quaint old expression - everyone knows that.
