I'm from California and I wouldn't generalize it as a xenophobic state at all. Most of the residents in the area in which I live are actually Hispanic and Asian. Keep in mind that California is a big state, so you can't assume your experiences reflect everyone else's.
By the way, I get the sense that this is a troll question intended to tee up some of the bigoted answers, because never in my life have I heard someone refer to themselves as a "Castizo American". Castizo is a colonial racial term that's rarely even used in a contemporary context in Mexico itself. Also no rational thinking person would ever assume that the state of Texas is free of discrimination when it was historically one of the most prejudiced against Mexicans.
@Brad The majority of people of Mexican descent in the U.S. are in fact legal residents (most are actually U.S. born). California has a Hispanic majority, but only 6.3% of the population is undocumented, and that includes a variety of Hispanic, Asians, and other groups, not just Mexicans. Only a xenophobe would automatically assume someone is illegal just based on their ethnicity.
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.
