Re: Has anyone else been disappointed by an author?
With as many authors as I read, it would be very unlikely for me to agree with the personal opinions of all of them.
However, a person's perosnal opinion, imho, does not invaldiate the quality of their work---or at least not always.
For another obvious example, many people do not agreen with Heinlein's political views. Despite that, he was, without a doubt, a major influence in sciencfiction for many years. Like him or leathe him, he--and Card--and L. Ron Hubbard--any many other authors do influence sf.
