Donbas, Kosovo, Scotland, Catalonia, Silesia (Poland) – should the principles of autonomy be equal?

If Kosovo could—why not Donbas? The question of whether regions with distinct ethnic and linguistic identities have the right to self-determination remains controversial, especially regarding eastern Ukraine. Advocates cite precedents: Scotland, Catalonia, Kurdistan. Opponents warn against legitimizing separatist movements backed by foreign powers. Is autonomy a universal principle—or a political tool used selectively? And are national borders truly fixed, or just lines until someone redraws them by force? Decide where your own boundary of acceptance lies.
