Do you consider nationalism a positive ideology?

Without colonialism, patriotic feelings aroused by one's culture, heritage and nation are perfectly legitimate. Traditionally, the fervor of anti-colonialism induced the pain of self-sacrifice, a divine rite of passage into nationhood. We must respect the fervor of nationalism in third-world and second-world countries. A reckless superpower, can, through the influence of a maniacal, evil and depraved inner circle, confuse us by mixing pure and good anti-colonial nationalism based in self-defense, with the preemptive evils of imperial colonialism. Modern examples include China and Tibet, Sadam and Kuwait, and the Imperialist Putin exerting his influence over the Syrians. Our divine obligation is to support third-world and second-world countries and immigrants if they wish to display their patriotism.
