United by Contempt

Geeky Libertarians and Fundamentalist Christians are strange associates until you think that both groups crave a world of purity--the geeks abstract, mathematical perfection and the bible-thumpers spiritual purity in unity with God. That is to say, death. In a way both groups despise life.

They despise matter and especially biological existence--because it's messy, mortal and flawed--so geeks with libertarian leanings find themselves voting with revanchist, delusional, literalist biblical outcasts seeking to restore an old, divine world order which never really existed. 

Or, similarly, the Confederacy. Contempt and feelings of superiority unite and define them. Bannon, Miller, McConnell and Ryan drip with it. Falwell did as well but now he's pure--or, rotting in the ground. The coalition is united by contempt. They hate themselves, their lives, and humanity.
