In my setting they have posters all around the school of pictures and drawings of children with different races, features and physical appearances, this is a form of inclusive education. They also have posters and boards with information about other countries, religions and beliefs and how the school is multicultural.
These people are holding signs that are general stereotypes towards their race. Whether people believe these things or not, they have a drastic impact on an individuals life. Stereotypes is an oversimplified fixed idea of an individual.
This reminds me of somebody very close to me. They have this and it hurts when other people just don't understand. So be loving to others just as you would to each other! You don't know what they have hiding underneath or are dealing with at home.
