Then you must be very happy that we will become free from Brussels.
Ordinarily yes, but lets not kid ourselves that the government we have gives us freedom over our lives. It seems that we have replaced a big government in Brussels that granted us certain rights, with a big government in London that is happy to take away some of those rights. I'm not sure how my individual freedoms have been extended by leaving.
In terms of hurt it depends what is meant. UK nationals may be 'hurt' due to lack of homes, increased hospital waiting times, or lack of school places due to an excess of non Uk nationals. I know that you believe that anyone should be able to go anywhere, but that ignores the fact that UK people fought for and built this country and they deserve to enjoy it.
It's hard to know how to respond to this. The British army that fought the two wars you refer to was chock full of people from throughout the Commonwealth, and indeed other parts of Europe. Only the other week I visited the memorial at Lazarky in relation to the London based assassination of Heydrich by Czech fighters. So the suggestion that our various wars were solely fought by British nationals is nuts.
Likewise, the country as a whole is great because of the people who live here. Our NHS relies heavily on migrant labour. Our Premier League and other sporting competitions relies heavily on overseas talent. The City of London is chock full of talented individuals from overseas, just as our universities provide fertile environments for the brightest minds from around the world.
So foreign nationals have both fought for this country and played a significant role in building it. Even overlooking the crassness of such a stance, the fact that stats have been thrown at you what must be 100 times that migrants contribute more in taxes than they consume, so if less of them are here, we have less tax money to spend on public services. The problem isn't that we have migrants, it's that we have a byzantine, centralised system of distributing funds to local authorities, who have little flexibility in reacting to population changes. If several thousand Brits moved to a small'ish town, they'd have just the same problems. We also have equally byzantine planning regulations that have been strangling house building for generations.
Neither of those things are being touched on at all as it's much easier to blame the foreigners. Shame. Shame on them.
