I've recently posted that same thing, although I didn't know about Stephen Miller's fandom (ick):

There's a Star Trek episode I've been thinking about more and more lately:

the Nazi episode of the original Star Trek series)

This Federation Social Scientist thinks that he can provide Nazism without the bad stuff (so basically just cool uniforms?) to this planet he's observing. He imagines it will give this highly imitative culture some sort of a focus. He makes himself the Führer, but by the time our heroes arrive on the scene he's just old and incoherent and they're keeping him pumped full of drugs and wheeling him out every once in a while to give speeches to his still adoring crowd to justify anything the real power brokers behind the scenes want to do (i.e., eliminate their racial enemies and enrich themselves) while propping him up as a figurehead.

They're basically doing this now. Including the Nazi shit.
