Fear , uncertainty and doubt are powerful tools when used by the unscrupulous. Fear can motivate one to hand over civil rights in a vain attempt to feel safe again. Uncertainty can be used to maintain a status quo that may be partially non-functional but preferable to what might come with change. And doubt is very powerful because it undermines the credibility of the target which makes it harder for them even defend themselves against the accusations.
There are people who live by the wanton use of FUD. There are media outlets that live, die and cry by FUD.
