OSC is a hack, always has been. I read a ton of Sci-Fi and could never get through one of his books from start to finish. Abysmal shiite.
I believe that says more about you, than it does about Card. While he may have despicable political or religious beliefs, the man is one of the best authors in the field. I can't think of more than one or two others who are as good at characterization (Spider Robinson perhaps, but who else?).
Not to mention that his politico-religious beliefs don't really seem to make it into his books. The Homecoming series has one exceedingly sympathetic homosexual character in a major role...just by reading his books, you'd never know that he's against equal rights.
