Which of the following best describes white nationalists' views on immigration?

White nationalists generally hold the view that immigration poses a significant threat to their racial identity and cultural values. This perspective is rooted in the belief that increased diversity through immigration can undermine the social cohesion and demographic dominance of the white population. They often argue that an influx of immigrants—coming from various ethnic and cultural backgrounds—may dilute what they perceive as a homogeneous national identity. This perception of threat drives their advocacy for restrictive immigration policies aimed at preserving their racial and cultural supremacy.

In contrast, those who support immigration, whether fully or in a regulated manner, do not share these views of fear or threat. They might advocate for the benefits of a multicultural society, which contrasts sharply with the beliefs of white nationalists. Hence, the correct choice accurately reflects the core belief of white nationalists toward immigration.
