That is a assessment commonly made by the people who have no clue about biology and Poland. Importing other races to Poland for the sake of that alleged improvement is a logical fallacy made by faulty minds guided or rather misguided by the false ideology.
I just took a look at Maxim's 2013 "most sexiest women" and it's funny how most of the women on the list are mixed.
In this case it seem to be driven by the fantasy world of filthy and depraved mind deeply injured by a prnography and all kind of sick stuff produced for some deeply unhappy and sick individuals.
