3 types of white dudes

[meesterperfect]

i live in a country that is not my native country.
there are not many foreigners here but the ones who do come here are 99% men hunting pussy.
sex tourists.

i notice there seem to be three genetic types of white americans.

english/irish types - very white, fair skin.
european types - ancestry from germany, poland, ect.
italian/greek types- darker skin, hair.

for some reason almost all out of the hundreds ive seen here are the english/irish type.
i wonder why but i do have an idea.
ive never met another italian descent foreigner here and i wonder why.

any theories?
