Can slander incite violence?

Like for instance, and please don't take this as anger, even though I'm angry at this jerk, but I will try to not let my anger get in the way of this objective. But say Michael Savage, who said autistic kids are fakers, now I hate that , fine. But let's just say that someone who loves autistic kids, and was extremely angered by his statements, fine. She gets so angered by them to the point of wanting to do something really bad to him. So she makes up a statement saying that he d her. Can that incite violence against Michael Savage?
