Stigma is a toxic, deadly hazard, which must be eliminated "Labels lead to stigma -- a word that means branding and shame. And stigma leads to discrimination. Everyone knows why it is wrong to discriminate against people because of their race, religion, culture, or appearance. They are less aware of how people with mental illnesses are discriminated against. Although such discrimination may not always be obvious, it exists-and it hurts." The stigma of mental illness is real, painful, and damaging to the lives of people with mental illness. Stigma prevents them from getting the treatment and support they need to lead healthy, normal lives. Many people don't want to be... labeled as "mentally ill" or "crazy." Stigma keeps people from getting good jobs and advancing in the workplace. Some employers are reluctant to hire people who have mental illnesses. Thanks to the Americans with Disabilities Act (ADA), such discrimination is illegal. But it still happens! Stigma leads to fear, mistrust, and violence. Even though the vast majority of people who have mental illnesses are no more violent than anyone else, the average television viewer sees three people with mental illnesses each week-and most of them are portrayed as violent. Such inaccurate portrayals lead people to fear those who have mental illnesses. Stigma results in prejudice and discrimination. Many individuals try to prevent people who have mental illnesses from living in their neighborhoods.
