You could actually read the thread I linked, instead of repeating a lot of assumptions I debunked there already. But whatever. You can have your opinion-- it's just that I think it's wrong. Not least in a moral sense.
No, I apply it to everyone, and as locally as possible. (My favourite country on Earth is Liechtenstein, which is already pleasantly tiny... consisting of just a handful of municipalities... each of which has a constitutionally recognised right to secede by democratic vote. It's almost perfection.) You seem to think that Polish economic interests correspond to "self-determination", but that's not how it works. That's why that map is so funny, and why you can't see it. Because the fact that Switzerland has no coastline doesn't give Switzerland a right to annex any part of France (except any hypothetical part that genuinely
wished to join Switzerland)-- just as the fact that Poland had no coastline didn't entile Poland to any part of Germany (except any part that would genuinely wish to be Polish-- which for sure wouldn't include Danzig).
Most, yes. And most should indeed go to Poland. But not all. Conversely, Poland should probably get some bits that stayed German in OTL. In the thread that I linked, I posted
this map as a rough mock-up of what an alternative proposal
might look like, aimed at more closely respecting the actual situation. (But do observe that this is not some "final proposal", but rather an indication of what things could also have been like, if "who actually lives here" had been the prime consideration.)
I genuinely believe that it does mean that. Or at least: that it
should mean that. You apparently prefer to
force people to stay with somehing they don't like, rather than letting them do as they wish and go their merry way. I'm sure many people think that way, but I find that such an attitude is the truly "wacky" thing.
