Right, so it is ok by you for some countries to treat people who were already living in their country and made their homes and livelihoods there, abiding by laws, paying taxes, different to say other locals who may also be from another country?
I have a friend who is from Poland originally, he is a self employed tradesman and has no truck with brexit and feels welcome here, his assures me his families life has not been made more difficult by the UK government since brexit, he just complies with UK law and seemingly loves his life here on the coast still.
If it was functioning as well for all as you imply, not all 52% (approx) would not have voted as they did, just a thought. The truth is politics is an ever changing environment. Brexit will see both positive achievements and some negative results as would remaining in some peoples eyes. I can still live and work abroad if i wanted to, I can holiday in Spain, France, Germany, Poland still. We can trade with the EU. They should concentrate on delivering for the lives of their tax payers rather than looking at ways to punish the nasty UK. They took their eye of the ball with the vaccines like we did on PPE. This is not like Animal Farm (EU legs good UK legs bad). We should all move on with life instead of getting stuck in ruts of disagreement, life is too short as it is.
