Boy, I never stop learning here at AD....when I lost my hearing, I had to transfer to a deaf school up in the mountains....it was "white" only...no Blacks or even the Blind.....
Now I'm thinking...."where did the Black deafies go to school?" (at that time)...I had never met a "Black Deafie" until many, many years later....and noticed no difference with their ASL....
I did meet a young Black lady at BK (Burger King) late yesterday evening with my son. She was the cashier, took our order. She knew I was deaf (my accent)...told me both of her parents were deaf, no speech at all...her signing was very slow and finger-spelling only....I did find it strange that her ASL ability was so limited, with 2 deaf parents.
