Maybe or maybe not. Many Latin Americans, especially Mexicans, are ignorant about their race. Many think Mexican/Hispanic/Latino is their race, and some think they're Spanish(white) when they're not.
He is obviously mixed with black, like some Mexicans. Maybe he knows it or maybe he doesn't. If he's like a Dominican or Puerto Rican, he'd probably deny it.
But maybe the Mexicans call him "negr0" or something, which would make him realize he's black mixed, but I don't know. There's no knowing for certain whether he knows or not.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
