"'Open the UK to unlimited immigration from Africa, and Asia'
So it is about race then afterall? You don't want lots of brown people here.
I'm mixed race and my DH is a white immigrant - Australian, but I'm probably more of an issue for you despite being born here.
By the way if no more immigrants are allowed here I'm guessing the rest of the world would retaliate and stop Brits from moving to their countries.
Also the country is not over-populated, the population is inbalanced as most of it is private estates and nearly everyone is crammed into the cities particularly in the South East."
The country is over-populated, we are the most densely populated large country in Europe. England would be the most densely populated country in Europe if it was country in it's own right. (not counting city-states). The southeast connurbation is ridiculously overcrowded, providing no quality of life for anyone but the most privileged.
I'm opposed to mass immigration of any race. Don't throw the "racist" argument about because it holds no water with me. I'm completely in favour of a small number of highly skilled immigrants being allowed to come to Britain to work.
If the rest of the world wants to stop Brits going to their country, fair enough. I can't see why they would. Skilled Brits have been working around the world for decades, long before we had unfettered immigration here.
