Intersectionality
Intersectionality says that the different ways people are othered and forced into a lower social position, such as racism, sexism, classism, ableism, homophobia, transphobia, xenophobia and bigotry based on belief, create an entire system. In this system, each of the ways people are held down by society contributes to the other. So if someone wanted to understand how a society began to other a group of people as a race apart from themselves (racialization), they would have to look into the ways that gender, class, sexuality, and other parts of identity shaped this process.
