I still like those books, and, for some reason, that didn't affect me. Other people, however, have. Science fiction/fantasy has a long, turgid history of weird and unsavory authors. I tend to ignore that.

I think books have a firewall between the author and the characters on the page. Actors, however, are a different matter. They are the medium.

I've always enjoyed H P Lovecraft and was disappointed to learn about his racism and xenophobia. AI tells me its was way beyond what was normal at the time.
