There are different racial groups throughout. The reluctance to identify as black is due to the effect of white supremacy. That same reluctance exists in this country. So, there's no real difference there. There's more of an opportunity to do it with latinos, b/c of the way we conflate ethnicity and race in those instances.

My father is Cuban, his father is racially black, his mother is racially white. He looks like a light-skinned black dude. On paper in the US, he's identified by his ethnicity as opposed to his race, but because his traits, he is viewed as black. He calls himself Afro Latino. So, I reject the notion that people will shy away from it. It depends on the individual. Regardless of how he wants to identify himself, American society decides how it wants to identify and treat him, so his racial identity is constructed extrinsically.
