According to the UN Britain has the highest percentage of mixed race marriages,relationships and children in the developed world so I guess we cannot be that racist.Perhaps when as many Polish women(in Poland) have black/asian husband and as many Polish men have black/asian wife as in Britain then you can say that Poland is no more racist than Britain.
Perhaps you haven`t realized that but our country since its beginning, more than 1000 years ago had been created by immigrants from various parts of the World: Western Slavs (Poles, Silesians and Pomeranians), Jews, Tatars, Germans, Ruthenians, Lithuanians, Latvians, Dutch, Austrians, Scotts, Armenians, Slovaks, Greeks, Italians, Gypsies. Hungarians and the French - all Poles have some ancestors as well as familynames who originate in one or more of those nations who migrated here in the past.
That, what you can see when you look at our people is a result of intermarriage of people from various cultures and religions (this is actually one of the reasons why Hitler hated us - "we aren`t being racially pure").
That, what is happening in the UK, happened here long ago - not without its problems - but I`d say - all in all - it ended in a succes - and it certainly didn`t involved any appeasing or political correctness.
