Stigma by definition
Stigma, by definition, is a mark of disgrace or shame.
Stigma has four components:
1. Labeling someone with a condition
2. Stereotyping people who have that condition
3. Creating a division i.e., a superior "us" group and a devalued "them" group, resulting in loss of status in the community,
4. Discriminating against someone on the basis of their label
