I thought Polish people in general were very nationalistic/patriotic?
Not really, they might talk big but that's about all. They are kinda similar to Americans, though different circumstances of those two makes it seems world apart.
Poles don't mention they are proud to be slavic or anything like that?
Poles do mention to be proud to be Poles but not all the time.
want to move to Europe (Poland) because I love European culture and lifestyle
Grass is greener and so on.
I want to learn Polish and learn how to read/write/speak like any other normal Pole
Good luck! :)
