Im pretty much of the school of artistic works stand or fall on their own merits. I like several Woody Allen films, he is a great writer/director. Ive read and liked Speaker for the Dead, and Enders Game, and maybe will reread them some day (still mean to get to Xenocide, too) and I havent really looked into what his antigay stance is, or what nuances if any lie there. Ive read and enjoyed the books of PG Wodehouse, Agatha Christie, Dahl, Yukio Mishima, Nietzsche, Mark Twain, and dozens of other writers who have been slammed for poisoned ideas, and not felt that my tender mind was irreparably polluted or that they were agents of spreading toxicity.
Card, in particular, does not seem to me, based on what I have read of him, to be advancing any homophobia (or xenophobia, heh) in his writing. Indeed, his antigay stance is quite surprising to me. So maybe I will just ignore that part of him, as I will ignore the racism, misogyny, and other prejudices that were pretty much baked in to just about every writer who was working before the late twentieth century.
