Exactly. As a culture, Muggles are rather...demanding. They want it all and they want it now. Could they learn that magic can do some things, but not others--like not bringing people back from the dead, but maybe helping cure injuries to people who are still living?

As for the revelation...I have no idea how it would be managed, but I'm inclined to go with good old-fashioned person-to-person oral storytelling. That method of relaying news has been reliable for millennia!

...I mean, that's not to say that the news media could be of no use, though.
