Consider that "moore UK authoritarianism" turned up zero relevant search results.

You shouldn't over-estimate the popularity of your favorite comic book authors.

“moore authoritarianism fiction author” is a more reasonable search and answers the question.

Your search also answered the question, in the fourth result or so.

Google tailors search results to you. When I searched up their search, it showed me nothing relevant as well.

"moore authoritarianism fiction author" worked though.

Yes and regardless the point is its some extremely niche author. The vast majority of anglophones aint gonna know him.

The author of V for Vendetta, Watchmen, 300, and The League of Extraordinary Gentlemen?

Well I (as a widely-read 81 year old bookworm lol) have never heard of him

Well now's your chance to familiarize yourself with the pop culture of 20 years ago. There's this other great book about UK authoritarianism, it's called 1984 by this little known author George Orwell.

Yes lmao. You think those are literary classics in the same vein as Shakespeare or something?

No, but the films made a billion dollars in box office revenues. I know of Alan Moore's V for Vandetta because of the blockbuster movie.

Ive seen one of those movies and didnt know any of them were from books.

You realize capeshit is for children and being overly inured to the silver screen is for basement dwellers, right? Right...?

You're not cool because you don't watch popular things

Okay, just to answer the damned question because apparently no one else felt like doing the decent thing and just saying it: the "Moore" mentioned is Alan Moore. https://en.wikipedia.org/wiki/Alan_Moore

I did initially wonder if the reference was to Thomas Moore!
