I think you may be assuming that ALL white people hate ALL Mexicans. That is not true. My sister in law is Mexican and I love her and her family.
She's an amazing, caring person and the fact that she is Mexican could never change that. Now, that being said, if a Mexican killed one of my loved ones, I would probably hate them, but would that make me racist? No.
I wouldn't hate them because they were Mexican, I would hate them because they were a murderer. Also, just FYI, the more politically correct term is Latin Americans, not Mexicans, but just to keep things clearer, I went ahead and used the term Mexicans.
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.
