As for the crime rate the perception is divorced from reality, I’ll quote from Wikipedia: “The United Kingdom's crime rate remains relatively low when compared to the rest of the world, especially among first world countries.” Our crime rate is a fraction of that in Ukraine before the war. Their murder rate is three times ours.
Maybe if you define immigrants with passports as Britons. There's a reason why the BNP, British National Party, won the two seats they ever won in counties most affected by immigration. This effect would also be exact opposite of that in Sweden, which is intriguing, because here the sub-urb ghettos are split between social democrats, which the immigrants vote for, and the nationalists, which the few non-immigrants left vote for.
The fact that you are trying to argue that areas affected are the least concerned, when the case is exactly the opposite across Europe; says a lot about your "reality". Modern leftists are a scourge.
A friend of mine tried that line about manufacturing on me a few years ago and I asked him what kind of factory he wanted his so. To work in when he grew up. He looked at me as though I’d just shot his dog. We don’t need factory jobs, we’ve git near full employment anyway. That’s why we need immigration to solve our demographic issues with our ageing population. We’ve got plenty of jobs much higher up the value chain, the main problems are around training and education.
