Let’s face it: Trump could dig up the deceased parents of his supporters for daily necrophilic debauchery while drinking the blood of the firstborns from each generation still living, and the supporters would just claim he was giving their parents heaven babies or some such.
Hell, Falwell Jr. would probably preside over affairs, sprinkle holy water and call it the new communion.
It’s not that his supporters are (overall) stupid and can’t see the connections – they just refuse to. And Faux News gives them just enough misinformation and obscurement that they can maintain enough plausible deniability to keep the cognitive dissonance at bay.
