A collective sameness

Watching the World Cup match France v Germany I am of an age when I am struck by the fact that France like England field so many black players, whilst Germany field none. Now to allow that thought to come into my mind I could, in some quarters be accused of racism and would be howled down for not understanding that the colour of the skin has no relevance in modern thought.
Without doubt there is no fundamental difference between what are euphemistically called people of colour and people of no colour (I am not sure where the Chinese and the Japanese fit in), that's us, but of course there are differences other than colour that set one group from another. The Kenyans  and the Ethiopians have developed a physiology that makes them the best distance runners in the world. Black short distance runners are clearly ahead of anyone in the white camp and we accept their superiority without question. Whether this is a racial factor or not we can all acknowledge their supremacy. In the playground children will drift into groups that are recognisable by their skin colour, its not a rejection of the one for the other but a bias that is, at its root the inherited mindset of people who recognise similarities and feel more at home, or at the very least feel there is one less a factor of  difference between them. Girls gather with girls and boys with boys for much the same reason.
The second generation immigrant born into a foreign country and a foreign culture will still carry his parents culture and allegiance, this is well demonstrated when his parents homeland cricket team arrive and the local side is swamped with support for the foreign team be it India, Bangladesh or Pakistan. The links and the self identification, part of which is the skin colour subverts any sense of the new nationality that it is argued, should be their new all consuming sense of identity.
When the German team play, and it is interesting that no identifiable immigrant plays for them, (even though Germany has its fair share of immigrants), they play as Germans who, through the ages were recognised as a race of white people. 

Teams with people who are but  a generation old in a country perhaps don't feel the same commitment to give it all unlike the the players from Chile, again clearly from old Chilean stock,  who worked their collective socks off to win. 
Perhaps we are too dismissive of those deep tribal affiliations that lurk inside all of us, in our obsessive desire to paint the human canvas with a collective sameness which we probe at our peril !!
