A million Irish arriving in Britain wouldnt be seen as as much of an issue for instance.
So a million of Irish wouldn't be a problem, millions of Pakistanis, Indians, Nigerians etc. weren't a problem but a milliom of "Eastern Europeans" ("news" about millions of Poles alone are sensational BS) obviously are a problem ? Very interesting indeed.
I dont know If you noticed that there is 0,5 mln of Ukrainians (working mostly illegaly) in Poland
Not really. 0,5 million is maybe the number of Ukrainians, who within a year worked in Poland - in most cases doing crappy seasonal jobs. The number of Ukrainians really living here is definately much smaller.
