There is no such thinking in Poland
What do you mean? You think that Poles should apologise to Ukrainians for things as far back in the past as 1018 but they shouldn't apologise to the Turks for much more recent events in 1683, for example? For denying them what they had been desiring for centuries? Are you an islamophobe? Or racist?
Besides, you're missing the point as usual. The point is to apologise to everyone for everything, and in this way become a moral superpower which will enable us to lecture everyone about minority rights, European values or tolerance as well as stop everybody's European funds on the basis that they are not democratic enough. :):):)
