People suffering from mental illness and other mental health problems are among the most stigmatized, discriminated against, marginalized, disadvantaged and vulnerable members of society. Although much has been done in recent years to improve the status quo, it is evident that a great deal more needs to be done to improve the moral standing of and to achieve social justice for the mentally ill. A key contention of this philosophical essay is that unless the stigma of difference that is attached to people with mental illness is overturned, their rights will continue to be marginalized, invalidated, violated and/or ignored.
