This fallacy is another personal attack, but it may not be against just the messenger.  It could be someone from their past or the person or group who first came up with this idea. If they can attack the origin of this question or belief, then they think they can defeat or confirm the topic without further fighting.  The term "Genetic Fallacy" refers to the act of criticizing an argument based on its perceived origin or initiator. In other words, people tend to ignore or give credibility to a claim based on its source rather than the claim itself.
