so, being born to white parents on a latin country, and being raised there, does that make you "latino" or "hispanic" or what?
If you're born and raised in Latin America, it makes you both a Latino and a Hispanic (Brazil excluded for the latter), regardless of the race of your parents.
Im aware that you can be white and have hispanic or latin ancestry. Joaquin Phoenix doesn't have any hispanic or latin ancestry.
You're right that Joaquin Phoenix being considered Hispanic/Latino is quite a stretch, as he was only coincidentally born there and was not raised as a Puerto Rican. However, you don't need Hispanic/Latin ancestry to be Hiapanic or Latin. If a Polish couple, for example, migrated to Latin America and had their children born and raised there, as Spanish speakers, they would be both Hispanic and Latino.
OP is calling for Hispanics to be cast in color-blind/neutral roles. Is it still representation when the character isn't culturally Hispanic?
Yes.
I consider it a race and I think that's something that will soon be accepted in the world. I'm Latin myself, and usually, we don't look like anybody else. He have very distinct features that define us, on top of having one of the most hugely popular cultures in the world. Thing is, there's different kinds of Latinos, and if they don't fall under white or black, then yeah, they are their own thing. It's pretty simple for me. I'm not white or black, I'm Latin. The world's bigger than just black and white.
It's not a race, and what you're doing is called erasure. You say we have "distinct features", but you're probably thinking about mestizo features, which not all Latinos have because... not all Latinos are mestizo. By trying to make Hispanic or Latino a race, you're excluding (thus erasing) the rights of Latinos descended from Africans, Asians, Indians, Polynesians, Middle Eastern and European to be called Latino and to identify as such.
Please don't do that.
I always took "Hispanic" to mean someone associated with a Spanish-based culture/background (whether that's Spain proper, Cuba, Argentina, etc..) and "Latino" to mean someone of Latin-American ethnicity (The Aboriginal/European/African mix that's common in South America). All Latinos are Hispanic, but not all Hispanics are Latino.
Hispanic celebrities like Martin Sheen, Cameron Diaz, or that girl from Blade Runner 2049 probably aren't what most people are thinking of when they call for more Hispanic representation.
No such thing as a "Latin American ethnicity". The indigenous/European/African mix you're thinking about is called mestizo. But non-mestizos are still Latino if they are born and raised in Latin America.
