In Canada, as far as I understand, the debate is about developmentally delayed, special needs, or a few others. It would be shocking to hear or to have people bring back the term 'retarded', not only because of the stigma but because it does not correctly describe the current information about brain development. That word was banned years ago here. As far as I understand DSM IV-TR, it is currently about 4 or more years old, correct? The only people I hear using the term retarded now are teens/young people who obviously have not been sensitized to these very amazing and wonderful people.
