sheafrotherdon has a really great post
over here with some resources to contact about the SG:U "Eleanor Perry" casting call.
I emailed the Disability Rights Education & Defense Fund this afternoon and came home to a reply from executive director Susan Henderson, agreeing that it's distressing, and indicating that they'd like to follow the trail. I sent her the spoilertv link, but if anyone has a more direct source, I am sure they would appreciate it. And YAY, it's on their radar!
