I think people mention roma and EE because its their presence that has been most noticed over the country as a whole...
I honestly don't know what your driving at op.
What most guardian readers do not seem to realise, is that the UK is not comparable to most other European countries in that its a small Island...it also has more pull factors than other eu countries.
All the main parties have admitted it was a huge monumental cock up, not to do what Germany and the other countries did when the borders opened and put work restrictions in place.
People see the effects of mass immigration with their own eyes...
Most people except a few die hards on here.
Also op, whilst its wonderful that you and many others have gone to other countries, thats that countries governments business.
The UK government has a duty and responsibility to look after its citizens and to allow sudden mass movements of people to live here, has not been the right thing for the UK.
I also find the argument that mass immigration is a good thing rather un savoury when countries like Poland are having a mass brain drain, as there is very little movement into the EE block countries.
Moan away about past crimes from western european countries but are you sure its not happening again when people are leaving poor EE countries, they are not benfiting from mass immigration are they?
