Because they are dumb. They want to keep using Hispanic/Latino as a race because it's extremely convenient for them. The downside of using Hispanic/Latino as races?
Well millions of them are now absolutely confused about their race. Millions of others think those are races when they're not. Millions think Spaniards are the same race as them, when they're not... in general.
Etc. It's just a lot of confusion and offensive stuff just because the USA wants to use Hispanic/Latino as races instead of mestizo, and educating Latin Americans on their race. Even the white and black ones don't know they're white/black.
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.
