I never saw anything in his books that was worse than anything I've seen in other modern novels and/or on TV and in movies all the time.

That's good - or alternatively, really depressing. But I'm in an optimistic mood, and am going for the positive belief that he managed to keep his more extreme beliefs out of his books (or perhaps they were written before his beliefs became this extreme? I don't know).

I'm glad this didn't spoil them for you.
