She won't talk about it because she knows, but the truth is just to frightening to face directly - the "truth" being that we've been controlled by psychopathic criminals all our lives and Trump has been our only respite in many decades.

Realizing that all the shit we go through just trying to stay alive doesn't have to happen and is, in fact, deliberately inflicted on us for control, is too horrible to consider. So they don't.
