Seems to me like the totalitarian regimes see themselves as realist. They just refuse to update when their "reality" does not match the territory. Killing the people who point out the difference is easier. Sometimes they change opinions, but then the new opinion becomes the "reality".
So I would say that totalitarian regimes profess realism. They just refuse the idea of updating, because they believe their map already matches the territory perfectly. And they also refuse the outside view, because they believe to be incomparable to others.
EDIT: Seems like I was probably wrong. I am not sure.
From Being a Realist (even if you believe in God):
My mother, who doesn't call herself a theist (I think she's agnostic), doesn't even accept realism. She doesn't even agree with this:
That's little more than tautologies here. Yet it elicited an impression of being forced to believe. I know because she told me about the totalitarian dangers from such narrow thinking.
I'm happy to have finally found the root cause of our ongoing disagreement, but now, how can I deal with that? It looks pretty hopeless, but just in case, does someone have a suggestion, or should I just leave it at that? (My ego doesn't like it, but giving up is an option.)
Now I'm relieved to know that in near mode, she's a complete realist. This craziness only shows up in far mode.
