A genetic fallacy appeals to something's origin. In classic terms, it is an argument that judges something as good or bad, valid or invalid, based upon where it comes from or from whom it comes. TDS is a psychological tribalism that is a direct manifestation of this fallacious form of logic, ie. "team jersey" mentality, that clouds the thinking of TDS sufferers. This corruption of reasoning is furthered by the less developed (or even nonexistent) critical thinking skill set of the average leftist mind. Combined this with their more developed emotional brain centers and you have the recipe for a perfect storm of oppositional defiance disorder on steroids.
