Why has race been such a divisive issue?

Race has been a divisive issue due to historical power dynamics, systemic inequality, and cultural stereotypes that have fostered mistrust and conflict among different groups. Social, economic, and political structures have often privileged certain races while marginalizing others, perpetuating cycles of disadvantage and resentment. Additionally, the human tendency to categorize and form in-groups can exacerbate divisions, leading to discrimination and violence. These factors create deeply ingrained biases and tensions that continue to impact societies today.
