Sorry, can you actually name a human being who had his "life/career" destroyed by a metaphorical snap of the finger? I mean, good grief, you have to dig like crazy to even find evidence of a false accusation.
I mean, sure, it happens, in the same sense that sure, you might get hit by a truck. Where does this outrageous paranoia come from? The horrifying thing is that you aren't alone -- half this topic is men posting about how terrible shrews are lurking in the bushes about to steal their careers. And... there are no shrews to be seen.
