My dad had a HUGE problem with fact-checking e-mails before 2003, when I finally showed him how to navigate Snopes.
A couple weeks after the WTC attack in 2001, my dad got this e-mail about the "lost prophecies of Nostradamus" depicting the attacks and passed it around to the rest of us, probably hoping to diffuse his sense of panic.
Now, I'm no expert, but I'd heard Nostradamus' quatrains only forecast until... what, 2000? If that was when they stopped, or when he thought the world would end, how the hell could he have seen further? Also, while his quatrains were often quite vague, I didn't think he'd be SO obtuse as to refer to buildings as "brothers" or to America as some "land of the eagle" or whatever the hell it was.
Luckily, it came out in the newsmedia that, yes, it was a hoax. Nostradamus never wrote it. And my dad finally calmed down somewhat.
Stupid, panicky spammers... scaring my parents for no reason and generally fomenting dischord...
That should be MY job!
