@Briancrc,
Good on ya, Briancrc. I was the Director of Administration at a nonprofit organization that provided support for the developmentally disabled. Early intervention helped them meet their maximum life time potential in what they wanted to do. What was interesting to observe and learn was that family members tended to help the disabled too much making them more dependent on others rather than making them more self sufficient. What is important to point out is that people who are ignorant about developmental disabilities do and say things that are offensive without realizing they have emotions like everybody else.
I have seen store clerks who have been patient with developmentally disabled people, and I have personally complimented and thanked them.
Developmental disabilities hits all peoples regardless of race, wealth, culture, or anything else.
I know that in Japan, the family used to keep them at home, because they felt shame. I hope that has changed.
