I have always thought Slavs as White. They aren't by American standards? How "White" is defined?
The native peoples of Europe. That's how I define it. Some people include Semites, for reasons I'll never understand.
This is what, in the US, most job applications "optional" diversity survey says:
White: A person having origins in any of the original peoples of Europe, the Middle East,or North Africa
The one I am filling out today includes south Asians and East Asians under Asian, and has another section for Pacific Islander. Pakistani is usually Asian though I've seen it listed as White on a city job application a few years ago.
We are sufficiently representing people to on occasion ask something like:
Which Asian: Asian Indian, Cambodian, Chinese, Filipino, Japanese, Korean, Laotian, Vietnamese, Other Asian?
And Native Hawaiian or Other Pacific Islander: Guamanian, Hawaiian, Samoan, Other Native Hawaiian or Other Pacific Islander?
Iranians, Iraqis, Saudis, Moroccans, Libyans, French, Germans, Poles, Bulgarians, Estonians, Finns, and Irish are just as white as the next under most US law. There are a couple court cases in which Arabs or Lebanese in particular were declared white. This occurred back when white was a privilege for immigration and probably legal protection and rights as a citizen. Asian Indians were almost considered white in one court case but this did not stick. Asian Indians are considered Caucasians (as an Aryan people) and South Asians. Mexicans were declared white by law some >100 years ago, and this was reportedly to improve the lives of Mexicans/Mexican Americans in the US as part of a trade contract negotiation. Many Mexicans may be white by virtue of higher European blood, though many Latin Americans (including Mexicans) are of sufficiently mixed race/Black/Native American blood to not be white. Armenians are white by virtue of ability to culturally blend in with whites (education and religion help) and I believe blend with white/Euro people by virtue of genotypes/phenotypes. This is similar to why Lebanese are white. There was also a movement among Armenians, Persians, and Arabs to not be white but other-write in ethnicity on the US census the other year so as to increase government awareness of the presence of these ethnic groups apart from dominant white America. I hope that such efforts make some inroads to recognizing the diversity of white cultural groups and their experiences in America and better address the needs of these communities.
To the OP: On medical forms, you may be a Slav. Outside of this, I would ask does it or did it much impact your life? Have you experienced a Slavic culture? How do you relate to it?
