Amos, I think you're being uncharitable. There's a world of difference between believing that it shouldn't be possible and not realizing that things like this happened. Morticia's comment certainly implies the latter, but not necessarily the former.Also she didn't SAY it was weird, she ASKED if it was weird, and how common it was.
I'd say she was being pretty open-minded. Your response, however, was far less so.
Calling 'em as I see 'em,
