@blatham,
Asymmetrically overgrown right amygdalas in the brain are the cause of conservatism. If the asymmetry gets any larger, the diagnosis shifts from "conservative" to "PTSD". This is why the right wing media keeps bombarding its audience with seeming crisis after crisis, all the while warning them that they must not stray from approved right-wing sources. To gain and keep right wing converts, the right wing has to mimic on media the high-stress environments that cause PTSD on the battlefield.
Conservatives are afraid if their rightie audience moves away from the conservative media onslaught, even for a little while, their conservatism might go into remission.
