There's long been an element in Britain that feels uncomfortable around brown faces or Polish accents. Now that the globalization of Britain is well and truly past the point of no return, these folks are shit-haemorrhaging all over the place at the Polish accents coming out of brown faces!
They want to roll back the clock...
Back to bangers and mash.
Back to warm beer.
Back to an era when Polish accents were heard in Poland and brown faces lived in the colonies.
Back to an era when the sun never set on the Empire!
... it's a little late to worry about all that.
