I think world unification is a good idea, so I support regional unifications as a way of achieving that. However, patriots are insane about this issue. It sparks instant symptomatic mental illness. If they like the idea, it's because they have a deranged conviction that it'd be good for putting their nation "on top". If they dislike the idea, it's because they have a deranged conviction that it'd be bad for putting their nation "underneath". The prevalence of lunatic patriots makes regional unification impossible. The nation-good retards throw fits either way, and it incites them to criminal idiocy.
Properly understood and implemented, regional unifications do not put anyone "above" or "beneath", but allow the freer flow of people, ideas, and resources across the surface of the Earth. Unfortunately, it is never implemented correctly. Human governments are corrupt, schlerotic masses whose evil is only outmatched by the corrupt, schlerotic masses called corporations. While corporate leaders are such idiotic primitive throwbacks to humanity's ancient ways that transferring power to government is generally a way to encourage development and moral progress, that doesn't mean governments actually do the rational thing of trying to help people with their problems. We can see in the case of German reunification that, in fact, the reunification did put western Germany "above" eastern Germany, leading to poverty and poor development as western German authorities flatly refused to take seriously the problems faced by the east Germans, despite a strong sense of ethnic unity between the two nations.
What lessons can we learn from that experience? Bare minimum, we can exclude all ethnic thinkers from the process. Ethnic homogeneity does not result in a properly implemented unification process, and it is highly likely that everyone who speaks of the process in an ethnic manner is contributing only noise. Ethnic homogeneity is not necessary. However...
