Every student and every instructor is different, and that difference is more than a single identifiable membership to a group. People have multiple identities and the intersection of those identities creates their unique world view. When stereotypes are allowed to be the lens we look through, we diminish that person, and limit who they are, because no stereotype is every complete. I consider understanding diversity to be a lifelong challenge, as nobody can fully understand how another person sees the world so we need to be open to learning from others, even our students, all the time.
