>>511160084 (OP)race is a spectrum with areas of >>concentration<< and border-areas where 2 differing ethnicities have higher rates of intermingling, whats determined as white depends on which definition you choose, which for most people is "white skin blue eyes and european looking", and if sam altman fits that bill then most would consider him white-ish in california.
if you choose to be less loose in the definition then he does not count, its the same way jews get punked in new york or are a bonafide "people" in california vs white people- theyre identifiable vs "white" people, and if you can be identified vs someone then by definition you are not that person.
theyre a semitic people that tend to be fairer complexioned than other semite subgroups.
