I think this comment (and my tl;dr response) does a better job of making my point. It's not that I think Gaiman is always bad, it's just that I'm no longer inclined to give him the benefit of the doubt.

I always wanted to write a SJ blog post on what to do and how it feels when you realize that, hey, your totally awesome liberal parents? Not quite as progressive as you wanted them to be. And maybe they still say some really fucked up, ablist, racist, sexist shit. And you love them, but there comes a time when they can't be heroes any longer. Pretending that -ist behavior can be explained away or justified is not okay, no matter who it's coming from. They're your parents, but to the world, they're being -ist jackasses.
