I think even if society was more understanding and tolerant, about differences and such....I would still have some functioning difficulties(so its a problem of the individual in that sense) and I think plenty of others would to. However society would be better equipped to deal with that and help individuals with their difficulties rather than ostracizing them or bringing them down because of these differences.

I'd say its a mixture of issues that make things difficult for the individual, but also society probably plays a role in how disabling a condition is.
