Why disabilities? please read in the post The Critical Analysis of Discrimination against Persons with Disabilities, as a top counter liberal discourse that developed in society and very strong constructed of ‘normal’ and ‘abnormal’. Thing that means ‘good’ and ‘not good’, ‘healthy’ or ‘sick’ ‘rich’ and ‘poor’. Maybe if you have a family or a child with disabilities, it is not easy to say ‘defective’ or ‘not normal’. Categorizing scientifically will give unfavorable impact because in the end, it could be regarded that society will assume that they are ‘useful’ and ‘useless’ after they got treatments from the outstanding educational institution or institution of rehabilitation of persons with disabilities.
