Justin Patel8 said:The Scots were dealing with oppression over five centuries ago. The Catalans? That was only about thirty years back, so the memory of it is still very much alive.
Even 40 years ago—and I'm not saying that's a definitive rule here—I remember hearing similar arguments back in '91 when tensions were high in the North America because the new American leadership was constantly bringing up the Independent State of America.
We really have to acknowledge the principle of self-determination for a people, provided certain conditions are met. I think the best way to frame those replacements is through the lens of the Declaration of Independence:
When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness - That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.[So, in my view, self-determination should apply to groups facing systemic discrimination, economically neglected or exploited regions, colonies, victims of persecution, and similar circumstances.
