If someone thinks that it is right being racist, xenophobic and a dick towards a whole nation just because some individuals from that nation were racist towards him.
Nobody is saying Poles per se are racist.
What witnesses are saying however is that some Poles in the UK, educated Poles at that, some of who I know personally, are discriminatory and xenophobic towards Asians in particular, and blacks, solely based on their skin colour and lifestyle choice.
As I've said before, us immigrants are always the worst offenders. I had some Asian gentlemen in customs at Coventry airport ask me "What the purpose of my visit" to the UK was. Even when faced with my British passport. He was guarding his country you see, like you Poles are "guarding" your adopted country of the UK.
It doesn't need guarding, so I think you all are safe to go back to your vodka parties and concentrate on other matters, and let the Asians get on with their lifestyle choices at the same time.
Are you taking about WWII Poles that fought for Britain and stayed there?
No, and that is clear to others. I think you would find that that generation was appalled at the EU wave of immigration, and either stay clear of them or (at least at first) exploited them.
