"The Furrtails, as part of her aim to integrate mentally retarded children into regular classrooms."
It doesn't work and smacks of utopia.
I don't know about that. When I was in school (1-12), we had all kinds of kids. Disabled kids, slightly retarded kids, kids with leg braces, kids with limps, whatever. They WERE NOT segregated, as you're implying they should be. They were just our friends.
Why do YOU want to isolate them? Can't stand looking at them?
