Through media, the potential for stereo types to build is a definite possibility. When a person, especially the young, is exposed to stereotypes of a specific group for the first time, then that person will assume all are that way. If the person continues to join with a group and receive many negative things, then it will affect the overall opinions of that person.
If someone hasn’t grown up around a particular race before then there are more chance that the person will racist other. The chances of racism will increase if any person had been fed negative stereotypes. Like, Parents teach negative stereotypes to their children, so they will follow what had been taught to them. It is important to live around different races, to determine the false stereotypes that they learned about.
Ignorance is the lack of education or knowledge. Some people grow up in a place where there are no different races, and they are fed with negative stereotypes about other races. Then, when they meet other races, they have the potential to be racist on other races. It is a lack of understanding and false perceptions about others which amounts to a lack of knowledge, which once again translates back to ignorance.
