The immigration over the last few years runs into many millions. I live in London. London had a population of about 8 million. It is now unusual to hear a British accent in my home town.
And many have left. Who decides what the population of London should be? Who decides what accents they have and what languages they speak? No one. It's a natural, organic thing which evolves. Why is it important that people speak with a British accent? Where do you draw the line? I'm from Newcastle, would I be welcome with my geordie twang?
I am saying uncontrolled immigration is not a good idea. There are only so many jobs, so many places in schools, and a limited amount of money available for the NHS.
Even if you were right on jobs etc, which I would dispute, who decides whether 'locals' should get priority for jobs, schools, services etc? If immigrants pay taxes, contribute to society, abide by the law etc, they should get equal access to all of these things. And the NHS thing is ridiculous. If you're against immigration because of potential increased impact on NHS resources, then logically you should also be against ageing?
Do you really think that Britain was insular, homogenous and conformist?
Of course not. Immigration is ingrained into the culture and history of this country. It's not a new thing. The only thing that has changed is the attitudes of people like yourself who are easily led by the media and others into thinking that people who do not speak or look the same are somehow less entitled to live or work in a particular place.
