Quite so. I studied a small amount of evolution as part of my degree and my understanding of the 'latest' thinking (mind you this was about 20 years ago so it could've changed since...) was that all us humans originated in Africa some two million years ago and that over the following hundreds of thousands of years we migrated all over the world. Like any other species, over time we adapted to our environment; people with dark skins didn't fare too well in the cold climate of Northern Europe etc (such as it was, we'd hardly recognise a map of the world as it was then). They couldn't absorb enough vitamin D and became ill, so via evolution, they gradually adapted as having lighter skins. This means that white people could be viewed as 'genetic mutants' so I'm surprised Nick Griffin isn't after eradicating us!
In more recent history, the British Isles have obviously been invaded time again from Scandinavia and central Europe and all other places besides so I genuinely doubt that ANYONE could claim to be a 'British aborigonal'. By Griffin's theory, even the Celts can't be British, surely, as they invaded thousands of years ago (from central Europe if memory serves but don't quote me on that...)
It's just such stupidity to classify people by their 'race' because in many cases it's a meaningless concept. I know both my parents were born in England but further back I have no idea; it's rumoured there's Polish, Irish and Russian blood in the family so presumably I should be sent back to one of those countries! It's idiotic 'policies' like that which confirm NG to be the ignorant simpleton that he is!
