Don't frighten me matyjasz, not everything you see in the movies is true
I only try to scare naughty boys, so if you behaved this year you don't have anything to worry about. :)
As for getting out knowledge from films, you are right it is very dangerous to do so, but than again, would you risk a statement that there are no white power skinheads present in Australia? Or better yet, that there are no tensions between people of different ethnic groups? Between Australians and immigrants? Before you do so, I will remind you about the riots that took place in Melbourne last year (correct me if it was a different city) where a huge group of drunk white youths ( I think it was about 1000 of them) started to beat every Arab looking people that had the misfortune to get in their way. It was as a result of beaten up two lifeguards by some Arab immigrants.
In conclusion, what would be the reaction of Poles when 600 000 immigrants landed one day in their country? My answer is, the same as any other nationality would be. Some would be ok with it, some would moan.
With poland in the EU, it will never be the same again. R.I.P
This image of Poland that you seem to display is only about 90 years old. Before the partitions of Poland, or should I say the Republic of Both Nations (Rzeczpospolita Obojga Narodów) it was a multinational country, with Poles, Lithuanians, Belarussians, Ukrainians, Jews, Armenians, etc.. living next to each other.
