White nationalism is a political ideology that promotes the belief that white people should maintain a dominant position in society. It often emphasizes the idea of a separate nation or community for white individuals, advocating for policies that prioritize their interests and culture. This ideology can manifest in various forms, including hate groups and movements that oppose immigration and multiculturalism. Supporters of white nationalism may argue that they are protecting their heritage and identity. However, this belief system is widely criticized for fostering racism and discrimination against non-white individuals. It is often associated with historical events and figures, such as the Ku Klux Klan and Nazi Germany, which have left a lasting impact on society.
