Bill, I believe that for a someone (particularly a celebrity) to prevail in a lawsuit like that, they would have to demonstrate it would be reasonable to believe that a normal person could be fooled into thinking that the impersonation was actually the person being impersonated...Impersonating someone for the purpose of satire is one thing; this is something far more sinister ... and I'm sure there is a law of some sort or another against it. With all the money Oprah has, she should be able to find herself at least one good lawyer and sue these assholes for literally everything they've got.
With lines like:
“This is the magical Negro, Oprah Winfrey, asking you to make my fellow negress..."
I think that would be a really big lift...
I'm frankly pretty puzzled as to what exactly the purpose of this robocall was, (unless as I suggested earlier, it was just to try to get publicity for the hate group)
Who was it targeted at? What kind of send list were they working with? Were they sending it to a list where they believed they would reach a large number of fellow racists just so they could all have a good har har har? Surely they could not have possibly believed that something this crudely over the top was actually going to effect any persuadable voter to oppose Abrams (quite the opposite; anyone like that would find the call repellent.)
If you genuinely want to try to persuade voters with a falsehoods, you send out some kind made up smear message ("Stacy Abrams is a member of the Communist Party", "Stacy Abrams has an illegitimate child hidden away she doesn't want anyone to know about", "Stacy Abrams is part of a kiddie porn ring", etc..) not this kind of obviously bogus vulgar caricature stuff that will fool absolutely no one...
This seems more like telephonic trolling or a robo crank call then any kind of real attempt to influence voters...
