Re: Freedom of movement.
As an 'out-er' I don't feel the issue of immigration is about 'stopping foreigners', and those that characterise the debate that way are only doing so to make a complex issue seem reassuringly simple.
The case for coming out seems to me about one of self determination and the democratic process. Under our own control, we would be in a position to decide how immigration should work in our specific case. I would hope that the democratic outcome would still allow for compassionate treatment of disposed people, and expect that it would also positively encourage immigration by much needed skilled workers.
The point here is that 'out' is not about pulling up the drawbridge or some xenophobic reaction to foreign nations. Britain outside the EU would still have the same deeply multicultural and broad political mix of people, and a democratically elected government that on the whole reflects the population. The discussion is not (and should not) be treated as though it were magically politically polarised.
