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 was 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.
