Tree-hugger?

To the outside world chemical sensitive people like the before mentioned may seem like weird tree-hugger. But what chance do they have? Who feels responsible for people like them, who cannot live in any normal house in a town or city because of the severity of their disease? Where do they go? Where are the dead spots where they can stay without pain? How can these people go  back to normal life? Is it correct that a society violates and ridicules those it made sick?
