FUD = Fear, Uncertainty, Doubt.
Lawyers use it it court cases too.
But mainly it is the realm of the politician.
Spread as much FUD as you can and hope you can distract the feeble minded.
Unfortunately, it is a “Thing” because it often works so well.
But it is also inherently the refuge and last recourse of the desperate who have nothing else to offer.
The reflex reaction of the intellectually bankrupt, immoral, mental midgets, and the lazy.
