The jews will take the example of a mulatto who is neither white not black, and they will conclude that race doesn’t exist.

The same problem happens when we try to define ethnostates by their boundaries. Usually, people are more or less the same on both sides of a border. So, instead of focusing on the borders, which are usually somewhat arbitrary, it makes more sense to look for the centers that are competing with one another. It can be the center of a linguistic area or of a particular culture. It can be a place where some traditions have survived, where the political and cultural dynamism is stronger, it can be a center of economic activity, and so on.

People who object to the independence of a particular nation usually point to the absurdity and arbitrariness of the new borders. But the borders are actually justified by the difference between the centers, and by the average difference between the territories based around different centers. Geographers probably used to study that before the universities were taken over by the Jews.

The wikipedia entry for the notion of border has a paragraph called “border studies” that says: “There has been a renaissance in the study of borders during the past two decades, partially from creation of a counter narrative to notions of a borderless world that have been advanced as part of globalization theory”.
