Just to be precisely - I'm very far from being nationalistic. I feel myself a patriot, kind of centrist or at least centre-leftist. And knowing our history, I'd say more - JUST BECAUSE I KNOW our history the Polish nationalism is so hard for me to understand. The "funniest" thing is talking about Catholic Church as the one that was the place where Polish culture was saved while all popes during those 123 years of non-existence were calling for obeying the laws of occupiers. Also the not-anti-nazi pope Pius XII wouldn't have rather supported Poles against Hitler.
Polish nationalism is also antisemitic - which is as surprising as Poles were on a similar way of being exterminated as Jews by Nazi Germany. Of course, there were Poles that collaborated with Hitler, as well as Frenchmen (Vichy), Brits (HRH The Duke of Windsor)...
And what's more important - Poland isn't that nationalistic as @Monzanator shows - the only truly nationalistic party would never have got into the Parliament without the coalition with other right-wingers - either Korwin-Mikke (you know, the sleepy old daddy from the EU Parliament) or Kukiz (rebelious, riotic rockman). The other "right-wing" has such a conservatinve, religious standards that it has two widows of the same husband (only one married in the church), the niece of the party's leader has three children, each with another man, not always the husband (there were also three of them I think), the chair of the Parliament's Family Commission has a child from cheating her husband... And is so anti-communist that the presecutor of the Martial law episode (1981-1983) became the judge of Constitutional Court last month. Not to mention such a Catholic mercy that their political opponents are called "communists", "thiefs", "worse sort of Poles", "treacherous muzzles" or "knaves"...
About the economy - the social programs, which are only to buy people's votes, because the country itself is not prepared for such a huge costs like 500 PLN monthly for every child, are so socialistic as they probably weren't even during the communism years.
No, @Olympian1010, I highly doubt you'll understand this nation. Quite a big part of it (about half) doesn't understand it either.
