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 might suggest looking for short-story collections that multiple authors have contributed to, then checking to see if the people you enjoyed have further works in the genre. I don’t read much pure horror, but an author I do read (Larry Correia) skirts the genre line sometimes, and has contributed to one or two anthologies you might find interesting:
Space Eldritch 2: The Haunted Stars (apparently, this one is the better of the two Space Eldritch anthologies)
Shared Nightmares
V-Wars: Night Terrors (I believe V-Wars has multiple anthologies and comic books, but I didn’t like the setting enough to look for more).
