I believe that when a concerted effort is made to separate people with the same disability it may come from a desire to prevent them from getting married and having children with the possible same disability. Get it? I'm talking about Eugenics. The act of attempting to get rid (die off) of "undesirable" people, who may water down the race. It's been going on for a long time in America, and I have to wonder if it's not a part of the plan to close the School for the Blind, as well as suspend the Oregon Commission for the Blind.
"Let's get these folks away from each other so they won't make disabled babies". Kinda makes you wonder, doesn't it?
