You are imagining things - there's no real separatist movement in Silesia, those who campaign for "independence", are just doing it as a practical joke, the same way some people in US declare their religion as "Jedi" and have some meet-ups, local fan groups, etc. Plus, there's only few hundred, maybe a thousand of them.

Please, do not give HN community the wrong impression that they are a real thing.

I mean, what's your main argument here, I feel like you haven't even addressed my main point?

Silesia is nothing like Catalonia - I know that because I live there (Silesia, I mean). There's no real support for the separatists ideas, because at the end of the day Silesians are not really that different from Poles - except maybe that they talk with slight accent and have a dozen or two of words borrowed from German. The concept of them demanding autonomy is as alien to me as the Switzerland demanding access to the Atlantic Ocean coast :)

EDIT: to be clear, I have nothing against granting them autonomy. In fact I think that getting rid of Silesia would solve most of Poland's economic problems :)

I never said their demands weren't ridiculous, but they do exist. I was expressing a view that countries wanting to leave EU should be seen with the same ridicule as Silesia wanting to leave Poland(as small and insignificant that number of people is). In an ideal world at least.
