To be clear, it doesn't bother me if the authors themselves are liberals, as long as the book/story doesn't have woke nonsense. In that sense, I guess older novels would be the best bet.
EDIT - Holy moly, thanks for all of the suggestions. I have my work cut out for me, looking into all these authors this summer.
I haven't really been a fan of horror since I came of age, but I read most of James Herbert's output when I was younger. If you've somehow missed him, then you have to go back and check, although be prepared for graphic sexual descriptions as well as horror.
He wrote The Fog , The Dark, Moon and many others. It's been too long to remember specific favourites, but just be aware of reading order in case you're jumping in on a book that's part of a series (eg. there's a Rats trilogy, a David Ash trilogy, maybe more). He also wrote some non-horror curiosities like Fluke (man reborn as dog; sounded so odd that I never bothered to read it, but it got a bad movie adaptation) and '48 (post apoc London setting where Hitler won WW2 using a bioweapon - more of an action thriller novel, somewhat un-based to the extent that nazi types are the bad guys but I have vague fond memories).
