white means european. it's not that complicated. this is something people have understood and written about for millennia. 'the white man' comprised european man.
"white" is a race. this is where "looks" come in. obama belongs to the black race because he looks like a negro.
the white american ethnicity is not a race, it is an ethnicity. other white ethnicities include german, dutch, swedish, etc. they all fall under the white race umbrella.
similarly, chinese, korean, jap, etc. all fall under the oriental race because they all look basically the same.
NYUUG pretends to be Korean. The truth is, he was born in America, is an American citizen, does not have Korean citizenship or a Korean passport and cannot speak Korean. He is living abroad like any other sad sexpat that was exiled from their homeland due to no romantic prospects. Since his ancestry is Korean, he could get Korean citizenship, but in order to do so, all Korean "males" under 35 must complete mandatory military service. Nyuug is a coward and won't do this, so he is still just another American sexpat loser and not a Korean as he constantly claims to be.
