ShinySideUp; I respect your opinions, and I totally understand why you feel the way you do, but I feel differently about almost everything you have to say, I'm sorry!
I wasn't really going to post in this thread anymore, but I have insomnia, so here I am, with my personal thoughts and feelings on the subject.
I think that, maybe, the difference between Canada's experience of immigration and the UKs might be one of attitude. Canada welcomes refugees and immigrants and makes them feel at home. This fosters good feeling, trust and builds strong communities.
However, in the UK, immigrants are told they can come here, come here perfectly legally and, in general, they're not welcomed. I know openly racist attitudes are uncommon, but none of us can deny they are out there, and immigrants in the UK see this stuff, just like the rest of us. They see they headlines in the Daily Mail, the Britain First posts on Facebook and, instead of feeling welcomed and at home, they feel unwanted and alienated which, in turn leads, not to strong communities, but fractured communities that are divided and characterised by hate and mistrust which, also in its turn, leads to separatism and potential radicalisation. Leaving the EU will not solve this.
Moreover, I don't think it's numbers of immigrants or refugees that are causing problems with housing, health care and the like. I personally feel it's due to years and years of chronic underfunding, by successive Tory governments that think you can run a country like a business, for profit, while I not only think you probably can't, I think you most definitely shouldn't, run schools and hospitals like that. At the same time as cutting funding to schools, hospitals, the welfare budget and inflicting an unnecessary period of austerity on the populace, the Conservatives have allowed an obscene amount of tax evasion, fraud and unfair and undeserved bonus/salary awards and turned a blind eye while their friends running the press ("When I go into Downing Street they do what I say; when I go to Brussels they take no notice" - Rupert Murdoch) peddle disinformation, mistruths and outright lies to demonise, victimise and make scapegoats of the most vulnerable and least able to fight back; the unemployed, the disabled, the immigrants. Leaving the EU is not going to help with this either.
I understand that people want change; I want change too, but I think the change we need to is change who, how and why we vote for the people we do, and whose best interests they're actually serving. I don't think leaving the EU is the way to get the change we need; Boris Johnson, Michael Gove, Nigel Farage; they're not change, they're more of the same; rich, privileged, white, public schoolboys who've mostly never done a proper day's work in their lives (thanks for the inspiration there, Mr Farage. What was it you used to do again? Oh, banker yes, that is a proper job, isn't it? Not like, say, a surgeon, or a teacher, or an army officer like those people in the EP you were insulting yesterday then... Oh, btw; thanks for insulting the very people this country has to now try and negotiate a good leaving deal with, very helpful...)
I do agree there are some huge issues involving both the EU and it's bureaucracy and with immigration, both legal and illegal, but I don't think leaving the EU really helps; for a start, we will almost certainly have to accept free movement of people if we want to stay in the free trade agreement, and the bulk of the refugee crisis is a UN issue, not an EU one. I don't think we can make a better, brighter future by shutting ourselves off saying "this is my bit and that's your bit". If you don't like the way things are run, you don't leave; that's just defeatist; you stay and you 'fight' (only in a metaphorical sense!) to make things better. We build a better future by coming together, working together, making all of ourselves better and stronger.
Don't get me wrong; I'm a proud Cornishwoman, and I'm proud of being both English and British. I love that we have Cornish Pasties and Melton Mowbray pork pies, and Stilton cheese; but I also love chicken tikka marsala, and pizza, and chow mein, and you can have all those things whilst still remembering that, as well as being Cornish, or Scottish, or British, or Pakistani, we're not only Europeans, we're most importantly human beings, global citizens. We are all brothers and sisters under the skin.
I can honestly think of no advantages we can gain from leaving the EU. I believe that we will only make things worse; become more separatist, more cut off, more disliked by our closest neighbours, and more irrelevant on the international and global stage.
I've heard a lot about 'taking back control' during this referendum debacle. Yes, 'take back control' but don't at the same time forget to ask, "what, exactly, are we taking control of, and who are we now giving the control to?"
