Seriously, if an author is completely mental, as far as his personal opinions go, can you forget all that and still enjoy their books?
If writing weren’t such an extension of an individual, I might say yes. It isn’t like acting, after all. Acting is reciting someone else’s lines, someone else’s vision. Writing is the person creating that vision.
It is an interesting question. Anyway, an author I used to like is completely mental. To be honest, I haven’t really followed him after the first two or three books of his. It wasn’t that I knew he was crazy then, but I just didn’t care enough about his books to keep reading. But, the ones I did read, I really liked.
