I think my view of who our own are may vary from yours.Personally I and most people know exactly who our own are without the need to reference a bit of paper.
Most people are proud of the job our Naval service does in the Mediterranean rescuing migrants. I wonder if they had to take the migrants they picked up back to Ireland instead of Italy and Greece would Irish people still be happy. Considering our history we are the last people on earth who should complain about immigrants and migrants.Of course the problem is 4 billion probably won't live/stay in Africa. Migratory pressure will build up immensely over the coming decades and countries like Ireland will have existential decisions to make.
Maybe if we don't want migrants in Europe we should trade with them fairly and stop starting wars in their countries.
