Don't get all upset...your African ancestors invented stuff too. I think one of your people designed a new type of hairbrush...oh and another one invented a portable pencil sharpener! So see...you can be proud too! *pats you on head
You are an Homo Sapiens, you descend from Africa. You are here sharing idiocy with the world because an African fucked one of your female ancestor! And your species motherland, invented: Counting systems (math), surgery, iron smelting, hieroglyphics (writing), domestication of sorghum and millet, coffee cultivation, early boats, celestial observatories, leatherwork, rock art, beadwork, jewelry...
An ignorant guy like you isn't a great data point for your "race" though. Of course, those who argue about the contributions of "races" are mostly ignorant and often racist in nature. Please don't speak for "whites" we don't like your message.
In nature and in evolution, diversity in a species is a survival advantage. A species that is genetically narrow has a high likelihood of extinction from environmental challenges.
In the UK one can escape diversity but retreating to rural areas, but they are gunning for these places too, so its not clear where one can settle on a permanent basis. If they had limited immigration to northern European countries such as Sweden, Denmark, Norway, Holland, Germany and maybe some Asian countries such as Japan or Hong Kong it would not have been a problem. Instead they opened the doors to countries that are totally incompatible to British values and the result has been disastrous. Britain has no natural resources. Its wealth was its human capital and by destroying that they have effectively destroyed its main asset.
Human capital... what a nice way to describe slavery, colonisation and appropriation. Why were the British so stupid to colonise these countries you don't find compatible with their value then? If they colonised Europe and Japan instead we wouldn't have to bear with this nonsense... The UK is already boring, cold and full of drunks. Without the foreign influence that you find "intimidating", it would just be a terribly boring sunless wet marsh.
