It's not bollocks. It's a fact. A fact as obvious as any other.
People move countries all the time? err yea?
It's not about exclusion. I'm all for immigration. I'd like to see, for instance, Doctors and Nurses from all over the globe come here in large numbers. I'd also like to see people have to have employment lined up before coming here, which is something totally in our control (but only) if we vote to Leave. That'd knock 77,000 off net EU immigration even before any other change in policy.
It's not about disliking 'the other' or anything remotely like that, for me the immigration issue is primarily about the ability of a society to adapt to the environment.
As I say, I'm all for immigration, I don't have a fetish for EU immigration tho. Why do you want to exclude the rest of the world? EU immigration is 50% and yet it's only around 7% of world population.
Overall, from my point of view, the primary argument to Leave is, as Tony Benn stated, a democratic argument.
Everyone has always talked the talk about Democracy. Well, now it's time to walk the walk.
