"(...) that mental retardation is no dishonor to anyone, and in a society like ours, mentally retarded children should go to school and get  prepared so that their lives could be as normal as possible.  No one is to blame.  Parents perhaps are if, for example, they fail to fully understand that during pregnancy, mothers-to-be should not drink alcohol.  Parents could have some responsibility, but children have none. There is mild, moderate, severe, and deep mental retardation".
