Dark vs. Right?

In my post below, I mentioned the Darkness and the Demons. These are my names for complex emotions, not literal things I actually see (and completely different from what Dexter experiences). I find people either immediately identify with this and no further explanation is necessary, or they have no idea what I'm talking about and think perhaps I need some drugs (or have been taking some drugs).

The most right-wing person I know personally cannot identify with the Darkness. When presented with the Darkness depicted visually in the arts (Munch, Burton, Gorey), they say they cannot imagine how anyone could possibly ever think of such things.

This leads me to wonder if there's a correlation between a person's politics and whether they experience the Darkness. I haven't done any investigation into this at all, but it does occur to me that it would be far easier to be right-wing if you knew nothing of the Darkness.
