Why? What significant difference does it make? Also families have churches and other venues besides the government to fill that gap.
Look, let's make something very, very clear. The IDEA is the law. What you think is right or wrong sitting there in your home is irrelevant. If your child was affected in this way, you would naturally want the best possible care, not a supervised daycare for a 17 year old. These parents and children deserve the same respect. None of these children asked to be born with a disability.
