Is there a difference between "ethnic whites" and "white people"?

Different ethnicities, sure, but they're still under the same racial umbrella. Slavs and Mediterranean people may be darker on average, but they are no less white than Germanics. Besides, the two groups are more closely linked than you'd expect thanks to interbreeding. Many Italians north of Rome are blonde and blue-eyed, for example, thanks to the Germanic Lombards.
