Ya ya. Keep confusing ethnicity with race.

A race is a grouping of humans based on shared physical or social qualities into categories generally viewed as distinct by society.

Russians are built different than Irishmen the only thing they've got in common is skin color.
There are Germans,Russians,Icelanders,Spaniards,Norwegians,Italians,Canadians,Americas,Australians,Scots, French,Polish,Bosnian,Irish,Swiss,Serbs,Swedes,Ukrainians,Belgians, and a lot of people from Latin America Asia and Africa who are white, they're not all the same race as much as you would like to think having similar skin colors would make it so. Their facial structures, body fat content, hair color,social tendencies are all different.
