Are the Russophone regions of Ukraine entitled to self-determination, according to Portugal?
I assume that Portugal believes it has a right to exist as a distinct entity, not unified as Galicia as it was prior to the Moorish conquest.
Are Ruthenians supposed to separate from Poland then? Or Basques from France and Spain? India, by that reasoning, should be splintered into about 25 countries. And as for Afghanistan, fuhgeddabout it. Furthermore, Louisiana and Quebec would have to separate from Canada and the US, because they speak bastardized French. How about China? It has one writing system, but several different linguistic regions.
It’s a fake argument. Hitler used it to grab Czechoslovakia the same way Putin is doing now.
