I’m not blind to the problems you describe, and nobody who loves this country can afford to be complacent about them. But it’s a huge leap from recognising those problems to concluding that ‘Britain is doomed.’ For a start, the patriots among us (still, I believe, the majority) don’t share the defeatism that implies.
Precisely. You are absolutely correct. So, we have immigrants concentrated in a few towns (out of how many hundreds of thousands of towns and villages in the UK?). It still doesn’t alter the fact that Britain is 92.5% white and the vast majority of immigrants to the UK come here to work hard and are very loyal.
