In the context of white nationalism, what is often viewed as a cultural threat?

In the context of white nationalism, low birth rates among white people are often viewed as a cultural threat because they are seen as indicative of a declining population that could lead to a loss of cultural identity and influence. White nationalists may fear that decreasing birth rates among their demographic will reduce their visibility and power in society, allowing other cultural or ethnic groups to gain prominence. This perception is tied to anxieties about demographic changes and cultural preservation, with the belief that higher birth rates among other groups contribute to the erosion of what they view as the dominant cultural framework.

The other concepts presented, while they may be relevant in different discussions around societal changes, do not align as closely with the specific fears associated with demographic shifts in the ideology of white nationalism. Scientific advancements and environmental changes, for instance, are not typically framed as direct threats in this context, and religious pluralism, although it can be a source of tension, is often more about ideological differences rather than concerns tied specifically to population demographics. Therefore, the focus on low birth rates reflects a specific concern over cultural continuity as perceived through the lens of demographic change.
