This initially filled me with rage, especially the part where the author says, esentially "Oooh. I didn't know you were blind. Whatever, you're still a bitch."
But then I noticed the author in question is signed with PublishAmerica.
Yeah, I'm an invisible minority and I like it that way (when I want to read about Jews I seek out Jewish authors, and I have no overwhelming desire to see myself represented accurately or sensitively or even fairly in sci-fi or fantasy), so this affects me comparatively slightly.
