ok so to answer this question is simple.Poland has never had any polonization policy towards people they ruled.germans always resettled people,destroyed or forcefully germanized (prussia,polabia,pommerania ,silezia.ect) Poland never cared of polonization of areas its controlled. didnt even tried to convert them into Catholicism.
Instead we have medieval catholic superstition, hatred and barbarism
not sure ,you even understand what you blabbing about.one might criticize Catholicism on many levels but as a culture input into nation its like a nuke bomb.
architecture,art,customs,traditions related to Catholicism is massive.
you say poland has no culture instead has catolicizm and therefore should go into science...got lost here
