harry potter and immigration:
Some have suggested that Voldemort’s obsession with purity of blood and ancient wizarding families is meant to suggest a reference to Nazi Germany. But the Nazis were not the only historical example of a group claiming the right to dominate others based on ancestry, birth or blood. Spanish Christians relied on the concept to justify the expulsion of Muslims and Jews in 1492, and the domination and enslavement of Africans and indigenous Americans thereafter. U.S. law uses the concept today to justify the exclusion of millions of people in the United States: non-citizens, or even worse, those it defines as “illegal immigrants.”
(...) It wasn’t always that way. Until the Civil War, U.S. citizenship was based on race rather than birthplace, and there were no restrictions on immigration. It wasn’t until after the Civil War that the concept of citizenship-by-birth was inscribed into U.S. law. Before that, whites could be citizens, no matter where they were born, while non-whites, which at the time meant primarily Native Americans and African Americans, could not be citizens, even if their ancestors were here long before any Englishmen arrived. People considered racially unfit for citizenship were welcomed, or even forced to immigrate, in the case of Africans, on condition that they and their descendants would remain a permanent underclass of non-citizens—physically present, but with few legal rights.
(...) But citizenship-by-birth didn’t mean the end of racial discrimination. It meant that lawmakers scrambled to make sure that those they considered racially unfit couldn’t take advantage of the new citizenship law. Almost immediately after the new law was enacted, in 1866, Congress began restricting immigration. Chinese, Japanese and then all Asians were only the first to be told that they couldn’t come any more, because the government didn’t want their children to be able to obtain citizenship by birth.
(...) What else can it be called, when millions of people are not allowed to work, not allowed to go to school, not allowed to live in certain places, not allowed access to all of the benefits that society offers to the rest of its members? When the police raid workplaces to round them up and deport them? When they live in fear that their very existence will be discovered, and they will be punished?
