What I learned from a peer review: White VS Mexican

So if you didn't know I am 1/2 Mexican and 1/2 White. There is most defiantly a battle between the two. During the peer-review I started to see the anger that my Mexican half has towards my white half. My father has anger towards white people along with the rest of that half of my family. My father tells the story of when my great grandmother was a little girl and the white man came and said if her family didn't move away then they were going to kill them all. My dad and his siblings would look at her and asked what her family did and my great grandmother would that she was here wasn't she. That they had moved. My dad is always talking like my white half looks down on me because I am a mix. I think that they are neutral but my I was taught anger so I react with anger. I have anger towards the Mexican half for the stereotype of being hard laborers. What is a girl to do?
