What this thread shows is that a lot of white English people really love being around other white English people well, erm, that just proves the point being made doesn't it?
It it only offensive if white people do it. It's understandable if non white people do it!
READ UP ON YOUR OWN HISTORY. Yes, sweety. That would be when we colonise other countries, not have them colonise us?!?! 
Sorry. The heated postings from any angle are amusing.
But yes, basically. I am white, English and would like to be able to be that, say that, live close to tohers who are also that... cos that is my comfort zone. Yes, I live in a multi cutural, small, rural town where English is not often heard on the streets, yes I have always had friends, colleagues, bosses of different nationalities and cultures, yes I do talk with them about the differences (although I have had one extremely tenacious poster tell me that that in itself makes me racist).
That notwithstanding, I am not 'agin' any of them and none of it means I need to lose my own natinal pride, be ashamed for saying that out loud, etc.
Again, we need to be much more NON PC, stop pussyfooting around 'sensitive' issues and just see things for what they are, differences.
