I have been trying to understand your point on race. You seem to be going out of your way to claim 'we are all the same' which is just ludicrous. If for not other reason than centuries of conditioning races are different.
As I mentioned earlier, as society continues to stabilize worldwide blending will continue until saturation. But as a planet we are a Long way from that.
The creativity and innovation that comes out of our differences is part of what formed our society. That is a good thing. It is not always pretty but you are living a Polly-anna life if you do not think it is necessary.
, no there massive diversity across the globe, but that diversity doesnt stop at national borders, unless there a physical barrier, like the Atlantic in the way, and then that only gets in the way up until the point that someone invents ship than can cross
there is a gradual change in people appearance as you cross continents and from one continent to another. that makes it impossible to say one race ends here and another one starts there
if you take only the slightest genetic change, which is skin pigmentation and say, this is one race and this is another, then what about all the people who have varring skin tones in the middle
a journey from say Scandinavian to southern African will see a slow transition of skin tone on your journey, so how many races are you saying there are on that journey,, one, two, three 100 ?.
there notable differences in skin tone and body type between Afro american? and east Africans, as there are between east Africans and west Africans are they the same race or not ? if so why, if not why in much the same way as i can identify those who come from the med from those who come from the Slavic countries,,, different race or not, but then i can generally pick white Australians out from a crowd of locals,, they look different ?
a lot of this is to do with the political determination of race in individual counties rather than there being any deterministic scientific point of change
in this country there a move to consider the Irish welsh and Scottish as different races, they are covered by the race relations act.. in american they would just get lumped together as white or European or caurcasion, so we have 4 more races than you before we even start splitting the enormousness variations there are across Europe and Asia. . in the uk the term Asian is almost exclusively used to denote those who ancestors come from the Indian sub continent, every one else is denoted by there country of origin and nobody accept Russians as being Asian
