Hello!
For my two cents worth, can't think of that much to add to what the rest have already said.
It's ideal naturally, when, as here, real native speakers can correct, at least your written, Polish.

The language is connected of course to the culture, as with any language, therefore, much of what is stated, written etc. in Polish is connected to the history/mystery (sorry about that one! he-he) of Poland. For instance, when someone sneezes at the table, one might hear "Sto lat!" = A hundred years! as the response, whereas in English the response phrase is normally "Bless you!".
Not a good idea though to judge either a language or a people by their politics. After all, the English are basically honest by nature.
