Are there regional variations in humanity? Yes.
Does it make one race better than another? Not really.
If you tell a liberal I don't see color there is only one race, they say you are racist for not appreciating all the different races. Make assumptions based on someone's race, and you're called racist. Don't assume their political views based on their ethnicity, and you're called racist - and those who hold views contrary to what the group is supposed to think are demonized. For example, conservative blacks are called traitors or not really black.
The irony of liberals saying they are fighting racism is that they then demonize those of European descent (racism), don't judge Arab Muslims by the same standards as Westerners because they are seen as backward (racism) which is why they don't get punished as when a white man rapes a child, blacks require a boost on admissions to college and jobs (racism).
