I do understand your concerns. However looking at your first point above, when you talk about migrants who have bypassed several countries to arrive here, and who can be "safely returned" it seems (and forgive me if I misunderstand you) that you are talking about migrants from outside the EU? - ie. those from war torn areas who choose to come to the UK, or economic migrants from outside Europe? If that is the case, then I am not sure how that fits in with this particular referendum, where leaving the EU will have no impact on the scenarios you talk about. If you are talking about EU migration, then those migrants have not actually 'bypassed' any countries to be here. We will continue to have illegal immigrants, asylum seeker immigrants and legal immigrants from outside the EU, regardless of yesterday's vote.
The UK is definitely a magnet for immigration, in large part due to our generous benefits system but through being part of the EU, we do currently have the right to return illegal immigrants back to their original port of EU entry. That right will most likely disappear once we leave the EU. Additionally, France allows us to have our immigration control situated in Calais to check the credentials of all those coming across the Channel before they arrive here. That right is also likely to be removed post Brexit. So we are in danger of losing some existing safety nets. However the UK will remain attractive to immigrants regardless of our non-membership of the EU.
Acceptance of refugees is totally separate to membership of the EU. In fact the UK has - and has exercised - an opt out from the EU directive on quotas for settlement of Syrian refugees. The number we accept is at our own discretion, no one else's. I am proud that we can offer refuge to those in need but for those who are uncomfortable with this, it is a domestic matter, not an EU one.
Re your second paragraph, I honestly can't argue against your point as I do not know the numbers of 20-30 year olds who have come to the UK and never worked. However, one of the few concessions that David Cameron managed to achieve in his pre-Bexit negotiations was the right to withhold benefits from EU migrants residing here for less than a specified period of time ( xx number of years, I can't recall the exact detail). So some of your concerns would have been dealt with in any case.
Your opinion is equally as valid as anyone else's (especially when it come to Ryan Mason
where we are in agreement) but I am not convinced that a Leave vote will result in any significant change to the immigration levels we have today.
