And also because you're wrong.
In our secular societies you are what your nationality is and your race is irrelevant (or should be considered to be) in the eyes of the state and in the UK it is considered rude to bring up someone's race (other than identifying them).
I will accept that we aren't perfect, but perfect is the enemy of good. Bringing up areas of Europe which I obviously wasn't referring to and have been politically unstable for decades now is disingenuous and simply missing the overall point to be a smartass.
