Yes, social unrest can be caused by exaggerating and spreading stereotypes about certain ethnic groups. Stereotypes are often based on simplistic and one-sided views, and when these are exaggerated and widely spread, they can lead to increased prejudice and discrimination. This practice can create or deepen misunderstandings, tensions and hostility between different groups, which can lead to conflict and social disharmony. Historically and today, channels such as politics, media, and social networks can be used to amplify such stereotypes, thereby influencing public opinion and group relations. This can not only lead to tensions between individuals and groups, but can also lead to wider social unrest and even violent conflict. Therefore, advocating cross-cultural understanding, respecting diversity, and strengthening education and dialogue to reduce the negative impact of stereotypes are important steps in building a harmonious society.
