"but there have also been millions of Poles who went to other countries for economic reasons: it's time for Poland to pay that debt off."
DEBT? Do Poles went to other countries to live in Welfare and suck money from government? NO!
Poles went overseas to work, to build, to contribute with another countries. They had LEGAL status. They build entire nations or states as the entire south of Brazil, Michigan or Parts of Australia.
If there was any debt, the progress that those countries made due to Poles already paid it.
It is absurd compare Poles that developed countries overseas with Sudanese or Somalian refugees that have no skills to help Polish society nowadays and will live using taxpayer money.
"Once more, Poland shows how selfish this country is"
So what do you suggest that Poland should do? Accept them all without restriction? Just Pakistan have 7 times the population of Poland. Should Poland just open the doors and accept as much as possible?
By the way, you, a great defender of gay rights, what do you think would happen if those 160 000 Somalians, Sudanese, etc (Salafi Muslims at majority) were allocated in a district and then a Gay Parade like the one that you praised passed through this district? I mean, do you know what happens with gays in Somalia or Sudan, right?
"Poles believe everybody owes them something ("daj mi") but they never agree to give a grosz"
The Poles gave their sweat, blood and tears, spilled in far away countries that they build in the last century. That worth more than any money.
My country included. Our greatest president, Kubiczek, was a Pole.
