That's modern bullshit. Northern Europeans are not more "ideal" as whites than southern Europeans.
And stature? I'm 194cm tall and the only other men in college who were bigger and burlier than me where black, not Scandinavian.
Whatever bigoted thoughts you have when you see Mediterraneans is your thoughts only. Greeks, Italians, and Spaniards have time and again been proven to be just as European as northern Europeans genetically, culturally, and linguistically.
