Before copying anything from this site, I would be sure it is OK to do so. Obviously, if it's an article that is online, anyone can copy that. If it's someone's post, then I definately wouldn't copy it without checking it out with the Admin and the poster.

That said, there are plenty of studies, articles, etc. online that can be found and copied or simply printed out for her benefit. Good luck in your quest to change her mind.
