Race vs Ethnicity Debate

Since race is not a scientifically meaningful concept, I assume you mean ethnicity?

Thought these were all nationalities and not a single "race" as you call it

Race isn't a discrete category. Ethnicity is closer to what you're describing.

Or Hispanic/Latin being considered a separate race from White. Doesn't make any sense

It sounds as if you're no longer talking about race but ancestral nationality.

One problem is when someone in the USA is 75% white 25% black people label them black. It's not that ethnic groups don't share common traits it's just the borders are so fuzzy it's going to be hard to narrow down specifics.

Neither is black or hispanic. The entire debate around 'race' in the US I find is riddled with outdated concepts and semantics. In many developed countries's dialogue on these issues the semantics rarely touch on race anymore as it's quite meaningless and scientifically untenable. Instead when we talk about different peoples in socioeconomic debates by referring to various ethnicities (which are quite flexible, you can group people on ethnic bases by culture, religion, langua

It's national origin based, not race based.

For me (a Hispanic) it's odd to see any race categorization at all, it seems like an obsession for both right and left wings in the US. Why does it matter so much? White and Hispanic is not mutually exclusive in a lot of cases, the same for Black and Hispanic or Native American and Hispanic, in most cases it's difficult to even set a race tag.

It isn't treated as a race in the US either, it's a separate question (so people can identify as white and Hispanic, or black and Hispanic, or other combinations).
