The UK is one of the most diverse countries in the world. And yet, we are not good enough at it. No one haranagues the Japanese as small minded island dwelling xenophobes, but us - despite our already very diverse country (white British not a majority in the capital city) well, we're easy targets.
EXACTLY this! ^ Every other country is allowed to want to keep their country as they want it, and to not want mass immigration, but when anyone in the UK even suggests anything similar, they are 'bigoted,' 'small-minded,' 'little Englanders,' and 'Daily Mail Readers,' and let's not forget 'thick and racist' and 'obviously voted for Brexit.' 
Such bullshit. It's this attitude (from some) that is part of the reason the LEAVE side won in the Brexit vote. 
The sooner we are out of the EU the better.

I couldn't agree more. It's my choice to live in a civilized country and I don't believe any country which has the death penalty can be classified as such, not to mention guns, shoot-happy police and far too many religious nutcases.
Yep, this too. Sooooo many reasons to not live in America, that it would take me half an hour to list them all! You have covered a few. Hell would freeze over before I'd ever live in America.
It's also utter bollocks that London is the best city in the UK. Utter bollocks. You can tell the people who have never ventured out of the south east of England on here! 
I will never ever EVER leave the UK, but if others don't like it here, they are free to leave. As a number of posters have said though, be very careful, the grass is not always greener on the other side. And as has been said, there is racism and bigotry in EVERY country, and you are deluded if think it will be any different/any better anywhere else.
Some people need to learn which side their bread is buttered.
