This could include Corsica, Wales, Silesia, Basque country, Scotland, Northern Italy and possiobly others.
Virtually all you mentioned (except Scotland) have no real claim to independence and no Europe would be bloody destabilized.
Free Silesia would mean huge economical difficulties for both Poland AND Silesia
No actually it would mean huge economic difficulties for Poland and MASSIVE income for Silesia, the only claim those bastards have is that they're greedy fvcks and autonomy would grant them mountains of money.
Furthermore, at least 50% of people living in Silesia are Poles
92% to be exact, the majority of Silesians when ask in a survey ticked "Silesian" and "Polish" or just "Polish", only 5% ticked "Silesian" only or other posibility.
I would also vote for Hessen flag, turned upside down ;)
Hessen got its flag wrong!
