If you're talking about actual literature there were actually loads of very right wing authors in history. GK Chesterton was an outright tradcath (and related to the fascist AK Chesterton), Borges endorsed military juntas, and Mishima died in a failed coup to restore militarism. If you extend that to non-fiction intellectuals then Nassim Taleb is a huge Ron Paul fan and his "black swan" theory is very accurate in describing COVID-19. I know barely anyone here reads anything that's not sci fi/fantasy genre fiction, though, so I'm more or less on my own with them.
Gonna be blunt, in my personal opinion, most "actual literature" written after the 1950's is pretentious and boring stories about boring people doing boring things and overwrought and insufferably highbrow prose with very few exceptions.
Granted, I do like some literary fiction but a lot of it's older works and most of my book tastes skew towards either genre fiction (not just Sci-Fi/Fantasy, but also horror fiction and gangster novels) or non-fiction books.
It doesn't help that 90% of modern literary fiction enthusiasts tend to be every bit as insufferable and cringe-inducing as the worst of genre fiction fans, but they also come with a veneer of social acceptability and intellectualism that makes their cringe even more pretentious and insufferable.
Like a lot of it comes off as tryhard, snooty, repulsively highbrow, and hipsterish.
But again, I'm a common blue-collar guy with commoner tastes and from the looks of your posts on the forum overall, you're probably in that 10% of literary fiction enthusiasts who's actually pretty decent and we seem to agree on a lot of things despite our polar opposite tastes in fiction and media, even if we agree from different perspectives.
So as always, take my words with a heap of salt and feel free to disagree with me on that specific issue.
My autistic side tangent aside, I do agree with you on your post in general, both the part about a lot of literary authors being right-wing and especially the part about anime and the history of the film industries in Imperial Japan and Republican China.
The earliest anime shorts have been dated from around 1916, IIRC. There were several anime short films from the 1920's as well that weren't Imperial propaganda and were mostly just meant as the answer to early Disney and Fleischer cartoon shorts.
It kind of reminds me of how the earliest Italian silent era "Sword and Sandal" films with Maciste were kind of the response to American silent era Westerns and
Quo Vadis being almost like the Italian equivalent of The Birth of A Nation in terms of its epic scope and that it was one of the earliest feature length blockbusters.
I kinda felt the whole "anime is post-WWII degeneracy" is just one of those autistic memes from the kind of anti-weebs that loop so far around they become every bit as or more cringe-inducing than the weebs they mock
The earliest anime ever released in America was a feature-length from the late 1950's based on the old folk tales of the ninja Sarutobi Sasuke and was called "The Little Samurai Boy" in America, since most Americans in the 1950's and 1960's saw samurai as honorable knightly figures and ninja as little more than common bandits and raiders.
It wasn't until the 1970's and 1980's that ninja gained their "badass cool" reputation in the United States
