We've got a mixed bag of coloureds here in Britain..

A nice negro type is usually innocently referred to as a "blackie" it's not meant to be offensive.
If people wanted to be mildly offensive they'd refer to him as a "black".
Brits refer to nice Indians and Pakistanis as "Asians".
They call nice Muslims "Muslims" and nice Somalians "Somalians"
But if any of the above groups are
not nice they get called n*ggers.
The Brits are a tolerant race but can only be pushed so far..
