Lydia may struggle academically, but she brings color, creativity, and compassion with her to school — and these should be valued, too! The presence of children (and parents) with a different view of life can be seen not as a threat but as a resource for realizing, in very real terms, the values of justice, rights, and solidarity.
While I do agree that students with disabilities should be accommodated for and seen as equal, I don't think full integration in the classroom might be the best idea. Students with higher levels of needs won't do that well in the classroom and need special instructors by their sides. They might also be bullied by their peers.
