Different forms of discrimination (e.g. based on origin, class, nationality, sexuality and age) cannot be separated from one another, which is what the term "intersectionality" aims to express. Intersectional theory aims to analyze different positions of social inequality and to show their overlaps, but also their interactions. A Muslim, lesbian mother can be affected by sexism, Islamophobia and homophobia and thus experience exclusion in very different situations. These discriminations do not simply add up, but lead to a very specific experience, for example not being addressed as a lesbian Muslim mother in an exchange of rainbow families.
