Quoting: uk_
We are not welcoming
I will accept that you are a British and your ancestors were British too.
But still, what do you mean by 'We'? Are you the Prime Minister Tony Blair? Or did you form any Political Party with such an agenda? ... Bottom Line: On which basis do you say that phrase?
I do not think that every immigrant (where ever they are from) enter your house. They probably work, earn, and live in their own places (inside UK).
You have something against them? You can say that you to your Government and request an explanation or appropriate action. Or stand for elections with your issues, and take polls.
Poland is not UK. I believe (which is logical) that all Poles, Pakistani, Indian, African etc who are rightful citizens of UK are your (respected and equal) Nationals. So, basically your arrival in the Polish forums, and commenting poorly of your fellow citizens is a proof of your bad taste. This also confirms that you are not good for UK, Poland or Europe overall. This can also potray your basic charectaristics and your attitude towards life. You view of the world, its nature and its motion.
Instead of your painful behaviour, you can allow yourself to think better. Understand yourself, our world (which all of us share equally) and our motion forwards ~ which is not stoppable.
I have a suggestion. You sould help Poles and people from other backgrouds, who are capable, honest and civilised in whichever way you can. At first you may feel it strange...but slowly it will give you more than what you will give to them.
God bless you... have faith in your ability.
