I've never read Orson Scott Card's writings about his political/personal beliefs. I've only read about them, and I've been reading about them for a few years now. Just today I read about them twice, both times in Salon. Both articles seem to have been inspired by Card losing a gig writing for Superman.

I know that I should be focusing on Card and the whole question of whether artists can be separated from their art. But what I am left thinking about after all this reading is, Wow, Superman is really, really important.
