His futurist political beliefs were ultimately silly IMHO, but I don't think it's fair to cast anyone who quotes his futurist writings as a fascist, let alone casting the entire movement in which the person who quoted him plays some prominent role as fascist.
I don't care how unpopular what I'm about to say is becasue it's true, but most "E/acc-ers" are ultimately looking for a world like star-trek, though even they admit it'll look most closely to DS9. I know of almost none who serious advocate for any kind of fascism.
Also, for completeness, looks like DEI is very standard and means "Diversity, equity, and inclusion". I didn't know that one either.
Ofc the “same acronym means 2 opposing standpoints” thing got confusing within hours, so they renamed it to e/acc and there ya go.
There’s nothing particularly effective about e/acc, they only needed the E to annoy the AI doomers.
AI doomers and e/acc I'm less clear on. E/acc is just straightforwardly very fascist. AI doomers seem to have much broader ideological underpinnings, but still seem overall aligned with the more moderate strain of the "technoauthoritarianism" we're talking about.
So sure, not everything fits into it, it's not all-pervasive. But that doesn't mean we can't talk about trends and inclinations.
