On the other hand, art does not exist in a vacuum and I really do have a hard time separating Card's homophobic views from his works; especially since, in retrospect they do creep into his books at least occasionally.
Just out of curiosity, where do you see this? For full disclose, I enjoy the works of plenty of artists, actors, and musicians whose personal views I find abhorrent. I enjoy Card's books (Enchantment is one of my favorite novels), and I'll leave it at that.
It's been quite some time since I've read many of Card's books, but if I recall the extended Ender universe has non-evil and non-stereotypical gay characters. The Earthfall books had at least one gay character who was good. One of the characters in that series (a scientist) even explained that homosexuality had to do with conditions in the womb and wasn't a choice (it's been a long time since I've read this, so I could be slightly off).
I've never read it, but Card's book Songmaster apparently deals with homosexuality to a large extent. I remember a friend of mine called it the "gayest" book he had ever read (she meant that in a positive way).
Where do you see Card's negativity towards homosexuality?
