Well, we agree that the formal definition of Asia starts at the Bosphoros and extends all the way to the Bering Straits but you've proved nothing by echoing my point about current usage.
Surely, you wouldn't want the British culture of using a term in its correct sense to be "overrun" by American or Australian slang.
You are simply playing with statistics for your own ends if you consider it to be a valid inference that 94% of white British people, who do not acknowledge active friendship with persons of other ethnic origins, also support your "repatriation" ideas or resent sharing their country with the others.
I've had enough of your hate - I know your opinions are your own and you have every right to have them and express them but...and I mean this in all sincerity...I hope that these opinions die with your generation.
For the record, I will continue to enjoy the diversity of the current British population and will associate myself with those who also appreciate this...including my friends whose grandparents may have come from another part of the world.
