B and C. It's not a disease--an autistic brain is a healthy brain, though it has developed differently. The disability is real, and should be allowed for; but disability is a normal part of the human experience, and differences like autism can be celebrated and held as part of one's identity. I am proud of being autistic--not because I think it makes me better than others, but because it's part of who I am and I like being who I am.
