The petition is sickening.
You don't like Scott Card's views on gay marriage*? Cool. Don't buy it. There's plenty of other Superman books by plenty of other people who are just fine with homosexual marriage. But to actively campaign for the man to lose his job because you disagree with him?? He has a right to his views and he has a right to make a living if he's good at what he does (having read Ender's Game but nothing else by him, I certainly would say he is going by that), just as you're free to not support him. And don't give me any of this crap about Superman being an icon and therefore, we can't have someone who doesn't have the same value system as us writing for him even though those views probably have absolutely nothing to do with the story whatsoever.
It's situations like this that make liberals seem as totalitarian and repressive as conservatives. Fight words with words. Make your point and make it clear; don't lobby for someone to actually lose their fucking job because you disagree with them. And because Sprouse has quit, not because he disagreed with Card, but because "The media surrounding this story reached the point where it took away from the actual work, and that’s something I wasn’t comfortable with," they actually succeeded in harming this man's job because they don't like his views on a subject.
*My own view is that the government should stay out of marriage period, but if they have to, then two men or two women (or three men, or two women and a man, or whatever any consenting, conscious adult wants) should be equal to anyone else who wants to. But that's irrelevant.
